Some of Hollywood's hottest took a trip north this weekend -- where they hit the many red carpets for the star-packed Toronto Film Festival.

There were a few noteworthy couples at this weekends' events:

-Brad Pitt and Angelina Jolie kept it predictable in matching black outfits, but set off a frenzy of fans and paparazzi as they made a rare red carpet appearance for the premiere of "Moneyball."

-George Clooney went public with his new rumored girlfriend Stacy Keibler -- and while they didn't walk the red carpet together, he did bring her to the premiere of "The Ides of March" as his date.

-Ryan Gosling may be linked to Eva Mendes, but she wasn't his date to the "Ides of March" premiere. That honor went to ... his mom!

Check out those sightings plus a red hot Megan Fox, a sexy Heather Graham and good-lookin' guys like Gerard Butler, Alexander Skarsgard, Seann William Scott, "Glee" star Cory Monteith and more!
