RiRi's Friends (AND Jay-Z) Urge Her To Go To Rehab!

But if this is true, sounds like her back is against the wall on this one!

Rihanna 's friends, loved ones, music industry peeps and more are urging the singer to enter rehab.

Jay-Z isn't too happy about her partylicious, wild ways either!

Those closest to RiRi believe her GORGEOUS looks and talented work are being affected by her lifestyle choices. Uh Oh...

A source says the Jiggaman even threatened to DROP her from the label.

The insider says:

"Rihanna has been out of control for months. She was supposed to catch a flight back to the UK last week [for a work obligation], but she ended up missing it, which was the final straw for management. She's not happy, but she now feels she has no choice."

We're not positive this is 100% true, but if it is -- hanging with Breezy probably won't help her either!
