This is just odd, but Joel Madden and Nicole Richie, who are about to have a baby, might be ending their relationship over Richie’s cup size. There’s probably more to it than that, but Jeannette Walls is repeating this story from Star: Seems Richie recently went to buy a bra in a lingerie store in Annapolis, Maryland, where Good Charlotte had a tour date. Richie asked for a size AAA, the smallest size available (she’s wee), but they didn’t have one, so Richie had to make do with an AA cup. When she came out of the store, Madden, who has a hair-trigger temper, “exploded,” erupting in a “very public, very brutal tirade,” berating her with abusive language and using the F word, leaving the flinching Nicster “stunned” and “submissive.” Good Charlotte, bad boyfriend.
