Ashley Olsen is "so in love" with new boyfriend Justin Bartha.

The 22-year-old actress and her 29-year-old beau - who starred alongside Nicholas Cage in 'National Treasure' and 'National Treasure 2: Book of Secrets' - are said to be smitten with each other, following a romantic Mediterranean holiday last month.

A source said: "It was a sudden plan to go to Mykonos and to explore Greece for a bit. Ashley is so in love and really happy with Justin, even though it's only been six months."

Ashley - who shot to fame with her sibling Mary-Kate aged nine-months-old when they both played the role of Michelle Tanner on hit US TV show 'Full House' - has reportedly already told her friends and family she thinks Justin is "the one" for her.

The source added to America's In Touch Weekly magazine: "Ashley has been telling her family how much she loves this guy and how sweet he is."

Ashley has previously been romantically linked to actor Jared Leto and cycling champion Lance Armstrong, who is now dating 'Fool's Gold' star Kate Hudson.
