Is anyone really surprised by this? Because I'm not.

From Entertainmentwise:

The pair are rumoured to have hooked up while both were in the South of France recently and although Chris still has a girlfriend, Vietnamese model Karrueche Tran decided during the meeting to 'give things a go'. "

Rihanna has wanted Chris back for three years now. And it seems there's no holding her back," a source told Heat magazine.

It isn’t just the public that the 'We Found Love' star has to contend with, it is her mentor Jay Z who has been staunchly against a reunion. The source added: "Jay travelled from New York to Antibes for dinner with Rihanna at Le Michelangelo restaurant on Friday July 27, where she apparently told him that Chris was the love of her life and she wanted him back."

Look...we've all been there before...taking back someone we know isn't good for us...so I'm not really sure what to think. She has to make the mistake, right?
