NEW YORK - The new most unlikely duo is “Full House” star Ashley Olsen and seven-time Tour de France champion Lance Armstrong.

The 21-year-old twin was spotted at the Rose Bar at the Gramercy Park Hotel on Monday night with the famous cyclist, reports Page Six.

“They came together with a group of friends. Ashley drank red wine, sat on his lap and they were making out all night. They left together around 2 a.m.,” the source told Page Six.

Access Hollywood has reached out to Lance Armstrong’s publicist and is awaiting a response. Ashley Olsen’s publicist had, “no comment.”

Lance Armstrong was previously linked to fashion designer Tory Burch. Lance bought a home in New York City to be closer to her. Before that he very publically dated rocker Sheryl Crow.

“He tried to make Tory happy when they were dating by buying a place here, but she couldn’t deal with him not actually living in the same city, so they broke up,” another source tells Page Six.

Lance and Tory split up in October.
