Shia LaBeouf and Carey Mulligan call it quits

Wall Street 2: Money Never Sleeps costars Shia LaBeouf and Carey Mulligan broke up after a nearly-secret yearlong relationship.

LaBeouf and Mulligan, who were first linked in August 2009 after being spotted smooching in a New York restaurant, split "some time ago," a source told People.

Now, since Mulligan had no place other than Shia's to crash in LA -- her home base is England -- she is shacked up in a budget Best Western hotel while filming her latest flick Drive.

"I was stunned when I saw Carey walking across the lobby," a hotel employee told MailOnline. "You would expect her to stay at the Four Seasons, not here. She is very easy-going. She hasn't made any special requests and doesn't ask to be treated any differently. She keeps herself to herself and seems quite happy here."

"She doesn't have a lot of things and lives out of a suitcase," said a pal. "She doesn't have too many friends in LA -- her closest friends are her publicists."

You can't be too careful in this economy -- even when you command $5 million per picture.
