Ashley Olsen dating Josh Lucas?

Ashley Olsen has been spotted getting close to Sweet Home Alabama actor Josh Lucas, sparking rumours that the pair have started dating.

The 21-year-old twin, who was romantically linked with 36-year-old cyclist Lance Armstrong earlier this year, was seen "all over" Lucas at the opening of New York's Museum on Wednesday.

Armstrong was also at the event, causing people to think that her public display of affection to Lucas, who is fifteen years older than her, was an attempt to make the sportsman jealous.

A source said: "They were meant to be watching one of the acts but they were cuddling up instead. She was all over him."

Meanwhile Ashley's twin Mary-Kate, who was hospitalised with a kidney infection last week, was seen partying at a club until 3am.
