Does Justin Have a New Girlfriend Already?

Less than a month after splitting up with Kirsten Dunst... Justin Long was seen introducing someone who looks like she could be his new girlfriend to his brother Christian at the 101 Cafe in Hollywood.

Geeez... this guy moves fast... we're still trying to figure out what happened with Drew!

A source inside the restaurant said Justin and the mystery girl were very affectionate and certainly looked like a couple.

Guess we'll be seeing more of her!
