Jennifer Garner: The Town in Toronto!

Jennifer Garner keeps it classy in Stella McCartney while out supporting husband, Ben Affleck, at the premiere of his new movie, The Town, at the 2010 Toronto International Film Festival on Saturday (September 11).

The 38-year-old actress recently topped the list at Parade as Hollywood’s hottest mom! At 32%, she beat out Heidi Klum (27%), Jessica Alba (22%), and Gwen Stefani (10%).

FYI: Jen sparkled in Cartier jewels — earrings and bracelets!
