Before everyone starts shipping for what could be Hollywood's coolest new couple of 2015, a source however was quick to point out that the two are nothing but good friends. At the most, there might have been some friendly flirting, but nothing more.

On the other hand, more eye witnesses report that the two were seen smooching during the said event. Perhaps that's still considered friendly flirting in Hollywood terms?

The party, which was held last Saturday, was a celebration for Nikki Erwin's 30^th birthday, whose boyfriend, Chuck Pacheco, is a friend of the Titanic star. Other celebrities who were there to celebrate for the occasion were Paris Hilton, Hilary Duff, Pamela Anderson, To Hardy, Naomi Campbell, Tobey Maguire and 50 Cent.
