Beyoncé wants to bump off bizarre speculation that she's not really pregnant.

The buzz started after photos and videos hit the Web that appeared to show her bulging mid-section to collapse as she sat down during the Australian talk show Sunday Night HD, suggesting she had a prosthetic stomach and that a surrogate was carrying her child.

But her rep, Yvette Noel-Schure, tells ABC the fake-bump rumors are "stupid, ridiculous and false."
