The actress, 34, who recently split with her beau of two years, actor Michael Sheen, was courted by the Toronto Raptors's velociraptor mascot on Monday night.
He presented the Midnight in Paris actress with flowers and a stuffed dinosaur as the Toronto public-address announcer introduced the London, Ontario, native to the crowd, who cheered wildly.
McAdams, sporting newly red locks, seemed charmingly embarrassed by the whole episode, but took it in stride, grinning her famous smile as she accepted the presents.
As NBA mascots go, the Raptor would be a prize catch for any Hollywood actress. Described as "165 lbs. of pure solid fur," he's been voted the most popular NBA mascot in each of the past three seasons.
He also "enjoys making people laugh, whether with him or at him, usually at him," according to his bio.
