Washington, Sep 26 : Hollywood actress Ashley Olsen is head over heels in love with Justin Bartha – and she’s making it very public.

Olsen flew to Las Vegas to be with Bartha, who is filming his upcoming flick ‘The Hangover’ there.

After a romantic dinner of sashimi and soup at Stack Restaurant & Bar, Olsen and Bartha partying up a storm with friends until the early hours at the Mirage’s JET nightclub, according to Pop Tarts.

Later the celeb couple went to the Bellagio’s swanky new Yellowtail Sushi Restaurant & Bar, where they apparently “couldn’t keep their hands off each other”.

“They were rubbing each other, hand-touching and there was barely a break in their conversation," Fox News quoted an insider, as saying.

“It’s pretty serious, Ashley is really comfortable with Justin. It’s a good fit,” an Olsen pal told Pop Tarts. (ANI)
