Cash Pissed Over Pap Invasion

Mr. Jessica Alba was p.o.'d yesterday, striking out when photogs stormed their quiet neighborhood.

The paparazzi were waiting for the couple to leave for Jessica's baby shower, but Cash Warren was the one clearly ready to pop, snatching the keys from one photog's car and taking the cap off one of her tires. The pap called the cops, but Casheroo eventually put the stuff on the mailbox -- situation defused.

Funny moment -- the pap seems indignant that we're filming her calling the cops!
