Britney Spears Admits Being Abused in Leaked AudioStar magazine's exclusive about Britney Spears being abused by boyfriend and former agent Jason Trawick seemed a little dubious ... until RadarOnline.com posted a telephone conversation that seems to prove it.

The tape is conversation allegedly between Spears and her former husband of 55 hours, Jason Alexander. Asked about problems with "fiance" Trawick, a voice reported to be Spears replies, "That f***er is not my fiance."

The voice attributed to Alexander says, "I thought he proposed to you or something at the beach?" Spears answers, "Before or after he beat on me?"

Star magazine's editor-in-chief, Candace Trunzo, tells PopEater: "After all Britney's been through, it was shocking and very sad for Star to learn that her nightmare continues. I hope she finds the strength to get out of this disastrous relationship."

UPDATE: A second tape has been released, detailing why Spears didn't file a police report. More after the jump.
