Since her early days on That '70s Show, we knew there was something about Mila Kunis. She's that rare combination of sexy, cool, and seriously funny — not to mention the girl can act. We fell for her dark side in Black Swan, and we love getting to see her take the lead as the guys' girl in movies like Ted and Friends With Benefits. She's been gifted with an uncanny ability to appeal to both men and women — with the styling skills to match. She knows just how to turn it up, slipping into a McQueen gown or Versace on the red carpet or dressing down in cutoffs and a tee with ease.
Now she's got her maternity style down pat, too, flaunting her baby bump in LBDs and casual separates alike. And we have to say we like how she looks with Ashton Kutcher on her arm, even when the pair is out for a stroll sporting athletic wear. To put it simply, after her year of major life milestones — Mila also scored herself an MTV Movie Award for her role in Oz: The Great and the Powerful — there's no reason for her not to be positively glowing. So, in honor of Mila's 31st birthday, click through to see why our girl-crush is only growing stronger.
