"I'll let you be—oh, should I save you from this?" costar Julianne Hough offered before her studly leading man was left alone to his Q&A fate.
"No, it's fine," Duhamel assured Hough. He then gave E! News' Jason Kennedy a simple "no" when asked if there was any new news to report on the family-planning front.
"You said it will be your greatest career achievement, so we're waiting," Kennedy laughed.
"Greatest life achievement," Duhamel promised.
Fergie, meanwhile, posed for pics in her curves-skimming Gucci dress and heels from her own line, but let her husband of four years work the carpet on his own.
