Kelly Osbourne is clearly feeling the strain of her parents' marital issues! Multiple sources told RadarOnline.com that the reality star and TV host caused a scene at L.A.'s Sunset Marquis hotel on Thursday night, after she unleashed a drunken rant. But even more shocking, a source close to Osbourne says she flipped out because she was sexually assaulted!

Osbourne was photographed in a heated conversation with a mystery man outside of L.A. Sunset Marquis hotel on June 16. Her rep insisted it was nothing more than an enjoyable night with friends. But according to an employee at the hotel who witnessed Osbourne's night out, "Kelly seemed wasted drunk and she was screaming and causing a scene."

The General Manager for the Sunset Marquis told RadarOnline.com that Osbourne acted appropriately at all times, and said, "She was absolutely not thrown out of the bar."

But a source close to Osbourne told RadarOnline.com that the true story of what happened is even more disturbing. According to the insider, Osbourne had spent the night at an auction, helping to raise money for charity, and continued on to the hotel to celebrate with friends. Said the source, "She was happy and celebrating."

As RadarOnline.com has reported, Osbourne has gotten in hot water before because of her spitfire personality. In Aug. 2015, she was blasted by fans when she tried to diss Donald Trump on air, yet ended up on the receiving end of backlash herself. "If you kick every Latino out of this country, then who is going to be cleaning your toilet, Donald Trump?" Osbourne said on The View. Latino groups smashed her for the derogatory remark.
