TMZ says sources have confirmed that New York actress and singer Jennifer Lopez is pregnant.
Lopez's representative did not immediately return TMZ's call for comment.
Fans and the media have speculated for weeks that Lopez was going to be a first-time mom.
The rumors were fueled when Lopez kicked off her joint tour with Anthony, wearing various billowy costumes that seemed to offer a glimpse of what appeared to be a baby bump.
The "ING Presents Jennifer Lopez & Marc Anthony en Concierto" tour is under way.
The couple is slated to perform in 14 major North American markets through Nov. 4.
Lopez's new album, "Brave," is also set to drop next week.
