Los Angeles: `Hangover` star Justin Bartha was spotted spending New Year`s Day relaxing on a beach in Hawaii with a mystery woman.
The 34-year-old actor spent the afternoon in Maui with the tanned, toned brunette, and they looked cool in a pair of matching shades, reported Us magazine.
The actor went shirtless while she opted for a pair of peach shorts and colourful bikini top.
Bartha previously dated Ashley Olsen for two years before the pair split in March 2011. His hit show, `The New Normal`, will return this season on Tuesday on NBC.
