The Portland woman met Bryant last April, and he asked her to deliver food to his room - where they had a consensual sexual encounter that stopped just short of intercourse, said the TV show "Celebrity Justice," citing unidentified sources.

But even if prosecutors can show Bryant is a habitual cheat, the woman could just as easily help him - because she says he was "a perfect gentleman" when she said no to intercourse.

Los Angeles defense lawyer Ronald Richards said such a witness might produce a zero gain for prosecutors and defense lawyers.

"I don't even know if the defense will be able to get this in - a prior act of good conduct," he said.

New York defense lawyer and former prosecutor Paul Callan said neither side would probably be able to call the woman.

"If he [Bryant] had a unique pattern, a unique m.o., yes. But as far as garden-variety picking up babes in a hotel, I don't think either sides gets it in," he said.

Bryant is accused of raping a 19-year-old hotel worker in Eagle County, Colo., last summer.
