Britney Spears went on a romantic weekend getaway with boyfriend Jason Trawick in Santa Barbara, X17online can report exclusively. And as soon as she came back to LA on Sunday afternoon, she hit up the Toy Story 3 premiere!

The "lovebirds" left town on Friday, making a stop at the Marriott in Calabasas (a trick they use to throw off the paps). Jayden and Sean Preston stayed home with dad while Britney and Jason shacked up at a beautiful Santa Barbara beachside resort for two nights before heading back to LA late Sunday morning.

As soon as Brit arrived, she had someone at her home doing hair and makeup before she headed to the premiere. The pop princess was looking way lovelier than usual -- but she didn't walk the red carpet! Why on earth would Queen B want to skip the photo ops when she was looking like a million bucks? We're sooo confused!
