Alright, if you're into celebrity gossip, especially who they're dating, who they have dated and why they broke up, then you'll thank me later. We tend to focus on the recent gossip like Selena and Justin and even go as far as gossiping about who Prince Harry is dating, but we usually always forget about who they dated before. Besides Brad Pitt and Jennifer Aniston. I won't ever get over that breakup.

There once was a time that celebrities were just struggling actors or singers, and they found each other that way. I swear, in Hollywood, you're not allowed to date people who don't have some kind of connection to the celeb world. Maybe it's the Illuminati? Don't get me started.

Now that all of these celebrities are even more famous, you'll definitely recognize their exes that they dated before you could even name both of them. Whether their choice now is a downgrade or upgrade, it's still hilarious that some of these people even dated. Let's just say Justin Timberlake's taste definitely got better.

Before: Justin Timberlake

Can you say random?! Actually, it's not really. This information only came out when Lifetime's Britney Ever After movie came out and it portrayed Justin Timberlake getting a little too close to Jenna Dewan in the club. She was his backup dancer before her big break in Step Up, but only admitted that they dated after the movie came out. Stating that their romance was more friend like, she also said that she was not a rebound from Britney. Girl, everyone is a rebound from Britney.

Now: Channing Tatum

Channing Tatum and Jenna Dewan met on the set of Step Up, which is one of Hollywood's cutest love stories. Now they have a daughter named Everly, and they often praise each other on Instagram just for being there. I mean, I love me some JT but this couple is #goals. I would definitely consider this a glow up, even though Channing Tatum has stated before that he's a 'high functioning alcoholic', but his wife puts up with it. They've been together for 11 years now.

Before: Matthew Morrison 

This is so random to me. Maybe it's because I live for Kristen Bell and Dax Shepard's relationship and only see Matthew Morrison as the music teacher in Glee. But whatever. The two attended the same college, New York University’s Tisch School of the Arts, which ultimately brought them together. They both wanted to pursue acting and dated for a short period of time. Kristen Bell actually talked about how much she loved the show back in 2010, and said he was her favourite part. Cute!

Now: Dax Shepard

Okay, this couple is goals. Not only because they're adorable AF together but also because even though they were engaged for a while, they waited to get married until California passed legislation legalizing same-sex marriage. They've been dating since 2007, got married in 2013 and now have two daughters. Awwww!

Before: Fergie

This made me laugh and I don't know why. Now, I find Fergie annoying as f*ck kind of annoying, but I genuinely can't see this relationship. JT and Fergie dated the same year *NSYNC came out with their debut album, and she had not signed on with the Black Eyed Peas yet. They were 7 years apart, he was 16 and she was 23. Maybe that's why I find this relationship uncomfortable?

Now: Jessica Biel

Such a cute couple. Anyways, even though the couple broke up for a little in 2011, they ended up getting back together and things have been looking up for them since. They've been dating since 2007, and married in 2012. They have a son together who was born in 2015. I've always found JT super charming and I personally love his voice so if he doesn't sing to her daily, bye.

Before: January Jones

When Ashton Kutcher was a model back in the 90s, they were both trying to make it as actors in Hollywood. They become huge stars, Ashton for That 70's Show and January for Mad Men but their relationship actually lasted until 2001. Apparently, it ended because Ashton Kutcher wasn't supportive of her acting. She revealed that he told her "I don't think you're going to be good at this" and she replied "f*ck you!". Ouch.

Now: Mila Kunis

Please for the love of God don't let this relationship ever end. I love Ashton Kutcher and Mila Kunis together, especially since he was her first kiss ever when she was only 15. After the show ended, they stayed in touch through AIM, but she never thought of him romantically until she ran into him at an awards show. The two started dating with no plans of getting married, and never wanting to. Now they're married with two kids and happier than ever.

Before: Conan O'Brien 

Before both of them had huge success, on Friends and as a late night talk show host, they actually met in an improv class. Actually, she thought she wasn't funny enough to act after that improv class and it was Conan that convinced her she was. How cute! They ended the relationship because they figured they were better off as friends, and have stayed friendly. She's been on his show a bunch now.

Now: Michel Stern 

Even though he was in a relationship when they first met, Lisa Kudrow and her husband Michel Stern have been married for 20 years! Funny story on how they met: He had just moved to America and was dating her French roommate, and she met him when he stopped by their apartment to pick up her friend. She said it was definitely love at first sight and she was pissed because the perfect man was taken. They met again six years later and the rest is history! They have one son together.

Before: Melissa Joan Hart

Let's just say that Ryan Reynolds has had a ton of super random relationships. From an engagement to Alanis Morrissette to marriage to Scarlett Johansson, Blake Lively hasn't been his only love. However, he did kind of date Melissa Joan Hart for a little while? The story is a little confusing. Ryan Reynolds was cast as her opposite in Sabrina the Teenage Witch film, which then became a TV show. He had feelings for her and even bought her an expensive watch, but she had a boyfriend and couldn't get over that he was younger than she was. They ended up kissing all night when she had a boyfriend but it ended there.

Now: Blake Lively

The most loved couple in Hollywood. This couple met on the set of Green Lantern but we're dating other people (He was married to Scarlett Johansson and she was dating Penn Badgley). They were very good friends and only found out their feelings for each other when they were on a double date, with other dates. They realized their were fireworks between them, and now they have two daughters. My favourite love story.

Before: Juliette Lewis

As one of Hollywood's most famous actors now, it's impossible to think of him when he was a struggling actor. But he was, and so was she. Before his big break in Thelma & Louise, Brad Pitt was dating Juliette Lewis who was almost 10 years younger than him. They actually dated for four years before they ended the relationship, and she claims that he was "wonderful, fun and smart". We definitely still see that, Juliette.

Now(ish?): Angelina Jolie

One of Hollywoods most loved and hated couples. Hated because everyone knows how they got started. If you don't, I'll give you a refresher: Brad Pitt was married to Jennifer Aniston when he was making the movie Mr & Mrs Smith and famously cheated on her with Angelina. It broke the hearts of millions of Friends fans, and gave both of them a bad rep. It seems like Brad did it again, as it's rumoured that the reason Angelina and Brad are getting divorced now is because he cheated on her with an unknown actress. Although, reports have been saying that they're trying to work it out for the kids. They have six kids together.
