Is Lindsay Lohan about to be a new mom — or is she just an April Fool?

The troubled starlet tweeted “Its official. Pregnant” early this morning.

Lohan didn’t follow up on the provocative pregnancy comment, leaving Twitter users to wonder if she were being honest, or just playing an April Fools Day prank after a long night of partying.

The “Mean Girls” star has been romantically linked to guitarist Avi Snow of the band City of the Sun. He didn’t make any comments about the situation.

Lohan was sentenced last month to 90 days in drug rehab for a reckless-driving rap. She has until May to tell the court where she will be rehabbing.

Lohan, fanning her own pregnancy rumors, caused a firestorm on Twitter, with blogger Perez Hilton jokingly exclaiming: “She be truth-telling tonight.” Calls to her reps were not immedately returned.
