Actor Leonardo DiCaprio and singer Rihanna were reportedly spotted flirting with each other at a party here.

The duo were caught in the wrong moment at designer Nikki Erwin's 30th birthday bash at the Playboy Mansion Saturday, reports eonline.com.

However, there are two contradicting theories where one states that they were 'just chatting' and the other mentions that they were getting intimate.

`No one was making out. They are just friends. That's it. There was a big group dancing. Tom Hardy, Naomi Campbell and a bunch of other people. Everyone was having a good time together. Maybe a little bit of friendly flirting but no scandal here," said a source.

Whereas, another source said `They were spotted smooching during the party`.

The party was also attended by celebrities like Paris Hilton, Hilary Duff, Pamela Anderson and Tobey Maguire.
