Many have been wondering why Chris Brown's been looking so despondant in recent days, and more than a few people have noticed his recent weight loss – and Sandra Rose is saying it's because of Rihanna!

The gossip columnist is claiming to have exclusive inside info on the dynamic duo, saying she reached out to Brown's handlers today to inquire about his unexplained weight loss.

Their response? A confidential informant confided that Brown is not on drugs - he is simply 'pining away' for his ex, Rihanna.

By not eating?? Hooookay. The source continued, Brown is despondent over his stalled career and his loveless relationship with girlfriend Karrueche Tran.

Wayminute – loveless?! Yup, loveless! He's only with her for his public image, she continued. He's not in love with [Karrueche], he's in love with Rihanna.

Sandra Rose also reported that the two stay in contact via texts and phone calls, and that they also subliminally tweet each other – which of course is not so subliminal, given that every tweet coming out of either of them is scrutinzed by the gossip rags for some romantic subcontext.

And here's the kicker: But both of the stars' handlers have informed them that being seen together in public would kill their careers.

And the public wouldn't be the only one upset about the relationship. A source told Radar Online that Jay-Z, who recently had a baby girl with Beyoncé, is deeply disappointed in Rihanna's decision to return to the man who beat her three years ago, punching her repeatedly on the arm and in the face, to the point of visibly bruising her face.

Jay was absolutely disgusted by what Chris did to Rihanna, the source told Radar Online. Last year at the VMAs, Jay-Z refused to clap for Chris Brown after his performance. Media reports claimed that Rihanna found solace in Jay-Z after the incident, but obviously she's had a change of heart, recording a song with Brown, cuddling with him at her Valentine's Day party, and reportedly secretly dating Brown for nearly a year, according to Us Weekly.

Bill Zwecker at the Chicago Sun-Times reported all of this months ago. Rihanna is still head over heels for Chris, he wrote, and that if it weren't for the media and her fans – referring to her so-called Rihanna Navy – she would already have taken him back.
