Sandra Bullock Makes Surprise Appearance to Pal Ryan Reynolds' 'Change-Up' Premiere

By
It's no secret that Sandra Bullock has been MIA from the red carpet lately, but the 47-yr-old beauty dropped jaws last night with a surprise appearance to 'The Proposal' co-star and long-time friend Ryan Reynolds' Los Angeles premiere of 'The Change-Up.'
Although the event was not a date night for the newly-single buddies, Ryan claims he had not one, but three companions (none of which were Bullock) for the night; his brother, mother and sister-in-law.
Bateman, clearly envious of Ryan's cornucopia of admirers pushed wife and mother of his child aside for the question, joking that if a real-life change-up were possible, he'd "change places with Ryan's mom tonight because Ryan is her date."
Watch the video to hear more from Ryan and Jason, plus who Olivia Wilde and Leslie Mann would have a "change-up" with if given the opportunity.
Don't miss 'The Change-Up' when it hits theaters this Friday, August 5.
