Rob on Cullen House Set, not in LA

According to a professional Twi-set Tracker Brie,

"Yeah, we left right before the rain really got going. We did see Peter Facinelli getting out of the suv, and then spotted Rob Pattinson in the next SUV that came up there. It was kinda cool, but it was getting dark, so pictures were nearly impossible from across the street where they kept us."

Unless Rob has Edwards running skills, E!'s report of Rob being in La at 100Monkeys concert seems false to me.
