Rihanna Instagram : Pantsless RiRi Pic Posted By Cousin, Rihanna Exhausted From "Diamonds World Tour", Split With Chris Brown? [PHOTOS]

Rihanna usually handles the risque Instagram pictures on her own, but this time her cousin Elle did the honors. Elle snapped the photo of Rihanna passed out and pantsless on her couch. The singer is apparently exhausted from the strenous schedule of her "Diamonds World Tour".

"Don't slip, Don't slip!!! @badgalriri slippin, I mean sleeping!! Lol! I real vex she still look kinda f-able! #ph-yodrool," she captioned the photos.

The "Stay" singer has over 70 shows left from now until the tour ends in Auckland on October 7 and the touring already appears to be weighing on the pop star.

On top of a hectic touring schedule, the rumored split between on-again off-again beau Chris Brown may be weighing on the Barbadian diva.

Chris Brown recently told Power 106 in Los Angeles that the couple was no longer together. DJ Big Boi asked Brown "Are you still with Rihanna?"

"No, that's the short answer," replied Brown.

Hollywood Life claims that Brown was spotted in Miami last Friday "pulling multiple hot women into his V.I.P section and serving them Hennessy V.S cocktails."

Brown and Rihanna haven't been able to see each other due to RiRi's world tour.

"I plead the 5th. You know I didn't lie to you man, I just didn't tell the truth. Man it has been a minute though, cuz I haven't had a chance to go out there on the tour yet. Cuz I've been working, but I seen her right before she went out," Brown said in the interview with Power 106.

What do you think? Should Elle have posted this pic of pantsless cousin Rihanna on Instagram? Are Rihanna and Chris Brown really through? Is RiRi feeling the strain of the "Diamonds World Tour"?
