The couple was seen shopping in Beverly Hills on Sept. 4th, and typically tiny Lavigne seemed unusually pale and rubbed her back while stretching. Whibley catered to Lavigne even more than usual, opening doors, and possibly watching out for his wife’s reported belly bulge. Lavigne’s reps have not confirmed a pregnancy, but even guests at the rockers’ recent wedding gushed about what “beautiful grandchildren�? Avril and Deryck’s parents would have.

In other news, Mrs. Whibley (who turns 22 later this month) was in New York for Fashion Week, and MTV News caught up with her at the Diesel show on Wednesday night, where she gushed about married life, her burgeoning modeling career, getting bitten by the acting bug and the upbeat album she's got in the works.

"It's so fun and cool to watch," she said. "The girls are so skinny. It makes me want to lose 10 pounds — I'm just kidding! But I'm like, 'Look at those legs!' "

"Married life f---in' rocks!" she said. "If you're with the right person, it's amazing."
