Rachel McAdams Spotted @ The Vow Set in Toronto

Rachel McAdams tried her best to stay warm Tuesday while on the Toronto set of The Vow. She's working on the romantic comedy alongside costar Channing Tatum while also embarking on a real-life love story — she and Michael Sheen confirmed rumors about their relationship by taking a PDA-filled walk around the city together! It looks like she's off the market once again following her split from Josh Lucas last year, while Michael was free to link up with Rachel after breaking up from longtime girlfriend ballet dancer Lorraine Stewart.
