InStyle Party Pictures of Jennifer Garner, Chace Crawford, Olivia Wilde, Ashley Greene at Toronto Film Festival

A glowing and energetic Jennifer Garner went straight from her TIFF Butter premiere to the InStyle and HFPA bash at the Windsor Arms hotel in Toronto on Tuesday night. The Tommy Hilfiger-sponsored party started late, but the stars were still eager to step inside and enjoy the festivities. Jennifer was joined by her Butter co-stars including Olivia Wilde and Ashley Greene, who could also celebrate the hugely hyped new Breaking Dawn trailer that debuted yesterday. Cute Adam Brody and Chace Crawford caught up inside the event after their red carpet debuts of Damsels in Distress and Peace, Love, & Misunderstanding, respectively. Anna Kendrick spent her day doing press for 50/50, during which she gushed about working with a few handsome co-stars recently — both Chace and Jake Gyllenhaal!

Jessica Chastain has been making the rounds while at TIFF, and this time she let loose with Katie Couric and Kathy Griffin. Jessica was in a black dress she actually purchased while in Toronto. Kathy stopped to chat on her way in and spoke to PopSugar US about appearing on her friend Anderson Cooper's new talk show this week. On the episode Kathy stopped by Anderson's place, and last night she reciprocated with an invitation saying, "Anderson can come to my house. He's afraid to, but he can. I have a chef. He will be fed like he's never been fed before. I like to call him chubby. He will be well fed and well loved."
