Jennifer Garner  is making the most of her time in Toronto, and last night was all about her new film Butter, which had its big TIFF premiere. Pregnant Garner arrived in Canada  on Monday, and she headed to The Weinstein Company's soiree that evening before joining up with her costars for a full Tuesday of press. Jennifer, Ashley Greene , Olivia Wilde , Alicia Silverstone, and their young castmate Yara Shahidi mingled at a cocktail party ahead of their red carpet premiere. As for an afterparty, the ladies hit up the InStyle/HFPA bash late night. Butter debuted to mixed reviews, so it's reportedly undergoing some editing before it hits theaters. The movie is still making headlines, though, since Harvey Weinstein formally invited Michele Bachmann  to the Iowa premiere of the satirical comedy, which takes unsubtle jabs at the Tea Party movement.
