Shar Jackson Sleeps with Britney's ex Husband

According to Page Six,

OH, no, she didn't! How's this for B-list logic: Britney Spears stole away Shar Jackson's babies' daddy, Kevin Federline, so Jackson has struck back by sleeping with Spears' ex-husband, Jason Alexander. Jackson showed up at the 25th-birthday party for singer Ray J, Brandy's younger brother, in L.A. Saturday night with Spears' redneck ex-hubby in tow. A spy says, "They made out all night before going upstairs to the off-limits bedroom area of the house." The rumpled duo rejoined the party an hour later, we hear - much to the surprise of Brandy and her new beau, Nick Cannon. A rep for Jackson declined comment.
