Joel Madden and his reportedly pregnant GF Nicole Richie are headed “vicious blowup” during a tour stop in Madden’s homestate of Maryland earlier this month. Star Mag snitches dish that the pair had a “very pubic very brutal tirade” and Joel laced Nic with an arsenal of ‘Fuck This and Fuck That’ while Richie sat in “stunned, submissive silence.”

The couple were in Annapolis bra shopping when the trouble started. Nic asked for a size AAA, the smallest size available, but they didn’t have it, so Richie bought one with a AA cup. Joel is rumored to a have violently bad temper:

“Joel used to be a nice guy, but his temper is flying loose these days,” a mole tells Star. “He’s overwhelmed, and he snaps because he’s got a lot on his mind. He finds fault with Nicole all the time.”
