The Mean Girls star has kept quite a private life from social media and is rarely snapped while out and about. She shares a son with her partner Jamie Linden, has a Netflix movie coming this year, and was recently seen on a rare public outing with her baby sister. Rachel McAdams' sister Kayleen Adams also works in the entertainment industry as a celebrity makeup artist and has worked on so many stars you know and love. The sisters were born in London, Ontario and grew up close by in St. Thomas. IMDb notes that Rachel who was born in 1978 is the older of the two, and their younger brother is named Dan. According to Celebrity Net Worth, Kayleen picked up a knack for makeup artistry while "assisting in the beauty department at Flare magazine". Later on, "she visited her sister Rachel on the set of The Notebook [and] she knew she had found her calling" from seeing a first-hand account of makeup artists at work.
