He may be passionate about Rachel McAdams, but Michael Sheen appears to have stronger feelings about staying out of the spotlight at the 2012 Toronto International Film Festival.

The 43-year-old "Twilight" star accompanied his Canadian girlfriend to the premiere of her fest film "Passion" Tuesday night, but stayed off the red carpet -- though not before one photographer got a sneaky shot of Sheen, dressed down in a mustard yellow shirt and a wine-coloured velvet jacket.

McAdams, who in her new film plays a seductive boss, had to make do with posing at The Elgin and Winter Garden Theatre and the "Passion" after party with director Brian DePalma. (Co-star Noomi Rapace is not attending the fest -- she already pulled her own solo red carpet appearance at Venice last week.)

The 33-year-old actress also flew solo on a Tuesday afternoon trip to Holt Renfrew, where she took part in a Variety Studio interview and posed for photos with filmmaker (and TIFF's "Aftershock" star, writer and producer) Eli Roth.

Though Sheen did not accompany McAdams to her "To the Wonder" premiere on Monday either, he reportedly played the doting boyfriend at the film's Hugo Boss/GQ-sponsored after party. The actor was spotted buying drinks for the table and posing for pictures with McAdams.

The duo has been dating for two years and rumour has it they are soon set to walk down the aisle.
