Now the Canadian actress, 33 – who has starred in Mean Girls, The Wedding Crashers, The Notebook and more – is again raising eyebrows for a possible romance. She was recently seen at a Toronto Film Festival afterparty with her Midnight in Paris costar Michael Sheen, 41, who last season memorably played Tina Fey's wannabe boyfriend on 30 Rock.
Besides the party, McAdams and Sheen also stepped out on the town – hand-in-hand – to take in art exhibits in the Canadian city. (Toronto happens to be her hometown.)
Describing the quality screen time he shared with McAdams in Midnight in Paris, Sheen gushed to Entertainment Tonight Canada last month: "All my scenes were with Rachel. Yeah, we had a great time in Paris. She's a genuinely lovely lady as well as being stunningly beautiful and very talented so, you know, she's got it all going on there."
Could the guy be smitten?
