Although a lot of people may argue that Kylie Jenner's pregnancy is one of the best-kept secrets of our generation, I would have to argue that Shay Mitchell's may have been just a little bit better. People were speculating for some time that Jenner was pregnant, but Mitchell's announcement came as a shock to everyone. Shay Mitchell's pregnancy has the Pretty Little Liars cast beyond excited.\nBack in June, the You and Pretty Little Liars star took to Instagram with a post that totally blew everyone away - not only because she was topless, but also because she was rocking a massive baby bump that she had managed to keep hidden for months.\nView this post on Instagram Does this mean I’m allowed to drive in the car pool lane at all times now?

"She kept it very, very, very, very secret. We knew that she was trying, but we weren’t sure until she told us.”\nView this post on Instagram beauties - - - #pll #pllships #plltheperfectionists #prettylittleliars #ashleybenson #hannamarin #sashapietersesheaffer #sashapieterse #alisondilaurentis #troianbellisario #spencerhastings #lucyhale #ariamontgomery #shaymitchell #emilyfields #sashay #emison #emisonendgame #sashaandshay #ezrafitz #tobycavanaugh #calebrivers #spoby #ezria #haleb #monavanderwaal #janelparrish A post shared by Sasha Banks (@sashabanksmkv) on Aug 7, 2018 at 6:43am PDT\n"I’ve seen her go through all these different stages and there was a time where she didn’t even think she wanted kids. She’s always been so independent and so strong and confident and I think that’s exactly what she is going to bring to the table with her kids. I think it’s so special and she’s just got such a big heart so that baby is loved already.”\nClearly, Pieterse is just about as excited as Mitchell and her boyfriend, Matte Babel, about the soon-to-be-born baby. Although she has no kids of her own yet, Pieterse is happily married to Hudson Sheaffer and said that kids are something the couple is looking forward to in the future.
