LOS ANGELES—Lindsay Lohan isn't going to be a mother, yet.

The actress confirmed Tuesday morning that a cryptic late-night Twitter posting hours earlier that stated she was pregnant was an April Fools' Day prank.

The "Liz & Dick" star's proclamation that she was expecting a child caused a frenzy on social media, and several entertainment news outlets reported the tweet while raising the possibility it was a prank.

On Tuesday morning Lohan deleted the tweet and wrote that she was having some fun. The actress wrote, "Where's everyone's sense of humor?"

Calls to Lohan's attorney Mark Jay Heller and her publicist were not returned.

The 26-year-old has until May to enroll in a lockdown rehab to satisfy her sentence in a reckless driving and lying to police case.
