Michael Sheen and Rachel Adams only had eyes for each other during a subway ride in Toronto.

Why bother waiting for hours outside a movie premiere to catch a glimpse of your favorite stars when you can just ride the subway?

One lucky fan spotted lovebirds Michael Sheen, 42, and Rachel McAdams, 32, riding public transportation around the actress' native Toronto earlier this week.

The onlooker snapped a photo of the hands-on twosome and posted it on Twitter, adding that the celebrity couple was "making out and hugging" throughout the ride.

While Sheen looked more hobo than Hollywood, with his unruly hair and overgrown beard, a sunglass-wearing McAdams was simple, yet stylish in a T-shirt, printed leggings and rain boots.

The couple continued their domestic bliss two days later with a trip to a local Whole Foods supermarket to stock up on food and wine.

McAdams is currently in the Canadian city with Sheen, where he is filming his latest movie "Total Recall."

Since making their red-carpet debut as a couple at the Cannes Film Festival in May, the pair appears to be stronger than ever.

Though their romance didn?t blossom until after filming "Midnight in Paris," Sheen credits the Woody Allen-directed film for sparking their relationship.

"I will be forever grateful that it was where I met Rachel," he told E! Online.

"She's talented, intelligent, beautiful. She's warm and friendly," he added to People. "She's very supportive, and very kind, very funny. She makes me laugh a lot."
