Is Rihanna's New Party Buddy Already Over Her?

A few days after partying with the pop star in London, former boxer Dudley O'Shaughnessy says he needs to focus on his career

Looks like Rihanna's new romance may be over before it even started!

The S&M singer got tongues wagging when she stepped out with fighter/model Dudley O'Shaughnessy in London last week.

Ri and Dudley, who costar in the video for "We Found Love," were snapped leaving Mahiki on Thursday night together.

But now the 21-year-old former British boxer is saying he's just too busy to date the pop star:

"We had fun together, but I honestly don't know whether I'll see her again," he reportedly told The Mirror. "I'd like to go to America...but for work."

Ouch!

"My career is the biggest priority right now," he said.

Silly Dudley! Doesn't he know that dating an A-list superstar is probably the best thing he can do to kick-start his own success?

Either way, we'll see RiRi and her party partner together again soon when the racy video for "We Found Love" debuts.
