Lindsay Lohan pregnant or pretending?

Lindsay Lohan had us all pretty worried there for a minute.

But it seems the troubled starlet was just joking around when she tweeted late on April 1st that she was pregnant.

The message simply read: "It's official. Pregnant."

But the post has now been deleted, letting us breathe a sigh of relief that LiLo won't be a mommy anytime soon.

In place of the freaky tweet, she wrote: "April Fools. Where's everyone's sense of humor?"

The pregnancy prank came just days after Lohan was photographed slumped under a table at a Brazilian nightclub.

The post was been re-tweeted by more than 10,000 users and quickly became a worldwide trending topic.

The 26-year-old starlet has been reportedly dating City Of The Sun guitarist Avi Snow for the past few weeks. But their time together will likely be cut short soon when Lohan is forced to spend 90 days locked in a court-ordered rehab facility.
