Rachel McAdams Goes Public With Boyfriend Michael Sheen At Cannes

More proof that life imitates art — Rachel McAdams is going public about dating her co-star in Woody Allen's Midnight in Paris Michael Sheen. In the film, McAdams' character cheats on her screenwriter boyfriend (Owen Wilson) with a pompous professor played by Sheen.

McAdams and Sheen walked the red carpet together at the premiere of Midnight In Paris. The two met on the movie set and have been dating for over a year without attracting attention. Last night, the happy couple attended the gala screening of Gus Van Sant's Restless, where they — and the rest of audience — gave the film a long standing ovation. —ERIK MEERS in Cannes
