Trey Songz is fighting back after allegations that he urinated on Celina Powell's friend without permission.

The 35-year-old singer, born Tremaine Aldon Neverson, was accused by Powell's friend Aliza of holding her hostage inside a hotel room. Aliza claims the singer confiscated her phone and purse, then urinated on her.

The allegations threaten to destroy Trey's career - or what's left of it. Trey pleaded his case on Twitter.com Wednesday.

"Y'all stay ready to believe a bird," Trey wrote, revealing messages exchanged between himself and his accuser.

The moody Sagittarius continued: "I usually stay quiet on this but I feel that in many ways the movement to fight for the women who actually have suffered harassment and abuse on various levels, has been hijacked by those who find it convenient for themselves to come up as they seek to destroy someone’s life."

He brought up other women accusing him of sexual misconduct, writing: "I brush it off everytime [sic] but once you have an allegation no matter it's true weight in validation, it's now happened once and to some will be believable from that moment forward. None of that happened.

"Y'all remember Jane Doe claimed I sexually assaulted her in Miami? She wants me to pay for her therapy and the rest of her school cause of 'all the trauma she’s been through.' Pls read."

"You will choose 2believe what you want. I've been focusing my energy and time on good things and I know the Devil wants my soul more now than ever," he wrote. "Ima keep my head high and push forward. If you holdin me down in these moments I preciate that. [sic]"

Trey, who shut down teh ghey rumors by fathering a son last year, concluded his case by retweeting, "Stop f*cking with low vibrations- You can't be spiritual and don’t know how the Devil works."

The reactions to Trey's tweets were mostly positive.
