RYAN & AMANDA
It was a Halloween to remember for Amanda Seyfried and Ryan Phillippe, who met at Kate Hudson's annual bash in 2010. "They're really into each other," a source told PEOPLE, after regular sightings of the pair together in L.A. confirmed their blossoming romance. But when Phillippe's former flame, Alexis Knapp, gave birth to the actor's third child in July, Seyfried moved on with New York real-estate exec Andrew Joblon.
