We've seen plenty of pregnant stars out and about lately, but we think Sienna Miller takes the cake for most stylish -- and adorable! -- mama-to-be.
The very pregnant actress was all smiles while out in north London Thursday, leaving a yoga class. She's expecting a baby this summer with her rumored fiance, Tom Sturridge, and she certainly has a beautiful glow to her these days.
Though Miller has stayed relatively mum about her pregnancy, she hasn't been shy about stepping out in all her pregnant glory. Last week she hit the town to celebrate her pal Robert Pattinson's 26th birthday.
Check out a photo of Miller's baby bump below, as well as other stars who are expecting:
