Does Ryan Gosling know about this? Us Weekly reports Rachel McAdams is back on the market after calling it quits with Josh Lucas after less than a year of togetherness. The "Notebook" beauty, 30, and the scruffy actor, 38, were first linked in January after they were spied kissing at an inauguration ball, a PDA trend that continued in the ensuing months, from tonsil hockey sessions over dinner in New York to lip-locks while strolling the streets of Toronto. Rachel, who split from Gosling in mid-2007 (they briefly reconnected in August 2008), appears to be working through the bust-up by showing some skin. She put her sternum front-and-center in a gaping white frock at the New York premiere of "The Time Traveler's Wife" on Wednesday night. "[Relationships are] hard ... and they're worth it," the actress tells OK! magazine. "If you find the right person, it’s worth the struggle." Your move, Gosling.
