Looks like the rumors of Britney performing tonight in San Francisco are false. Our boss man saw her with his own eyes today, in the car near a Beverly Hills park with both kids in the car (he thinks she wanted to stop but there were too many paps around). So instead of a big show, she's at home being a mommy tonight.

And I also got some more details from an inside source, that staff at the Red Devil Lounge in San Fran thought they were booking Britney when someone they now believe to be an imposter, booked the space a coupld weeks ago for the M+M's for tonight. They started to prepare the venue and advertise for tickets but when they didn't hear back from the supposed Britney staff member, the peeps at Red Devil started getting suspicious and the pulled the booking. I've been told it's a small carpeted stage with limited lighting that's more appropriate for Fishbone than for Britney ...
