The Ferghamels have liftoff.

Less than 24 hours after their fantasy nuptials, Fergie and Josh Duhamel were at LAX airport with bags in wedding-banded hand. The casually dressed couple was clearly headed on a tropical honeymoon.

And it's already time to cue the baby rumors.

Despite the bride's tight, high-waisted jeans, a paparazzo dared to ask if the Dutchess was expecting.

"I'm pregnant with twins," Fergie, 33, joked.

The "Glamorous" star's mother, Terri Ferguson, told E! News' Ryan Seacrest's this morning gushing about the event and saying her daughter has "never been pregnant" but, with all the rumors, "Josh's mother says, 'Would she hurry up and have that elephant,' it's such a long gestation period."

Uh-huh. We all know the truth is oft said in jest.
