THIS IS JUICY!!

So we all saw those pictures of Britney Spears outside Kevin’s house the other night… He wouldn’t let her in, she lost it, went to wack a photographer’s SUV with an umbrella… then she and her assistant drove away.

WELL, according to Star Magazine, Britney would have REALLY lost her mind if she knew SHAR JACKSON WAS THERE!!!!

Obviously Kevin can’t take care of the kids himself, so he called his ex Shar Jackson to come over and hang out… and Shar’s been playing mommy to Britney’s kids!!!!
