USHER - USHER AND BROWN IN RIFT OVER BRITISH BEAUTY

R+B singers USHER and BOBBY BROWN haven't spoken in nearly two years - after falling out over the YEAH! singer's attraction to a British beauty.

ZENA - who was one of the original members of girlband MIS-TEEQ - attended Usher's 23rd birthday party in Los Angeles in 2002 with Brown, whose THUG LOVIN' video she starred in.

And the gorgeous 23-year-old, who is just launching her solo career, has revealed Bobby flew into a rage when the BURN hunk tried to make a move on her.

Zena says, "I was working in LA and was invited to be in Bobby and JA RULE's video.

"He took me on a private jet to Usher's birthday party and when Usher said something to me, Bobby acted very fatherly and protective.

"They started arguing and were pushing each other. I think they'd had too much to drink. Bouncers had to split them up. I felt embarrassed for them."
