Justin Timberlake and Ashley Olsen: New Couple Alert?

Justin Timberlake and Ashley Olsen may be dating, Us reports.

They're both newly single, they're both former child stars and they both have their own fashion labels. Pretty much a match made in heaven right there.

The celebrity gossip source does cite some actual evidence (term used loosely), claiming they've been inseparable (and flirty!) in and around NYC of late.

We heard the same about Justin and Olivia Wilde, but hey ...

One insider close to the pair (spotted together at the Greenwich Hotel, an SNL afterparty, two Broadway shows and a polo match outside the city) says:

"They are hooking up."

Consider us sold. Adds another source of the twosome, who both recently ended previous relationships: "They're really trying to keep it on the down-low."

An Olsen source says that the former sitcom kid turned fashion mogul is "aware of Justin's reputation with women, but...They're in the same head space."

We're not sure what that means, but it sounds HOT!
