Lindsay Lohan-Posing Or Pregnant?

Lindsay Lohan has the social media world buzzing. She reportedly told her followers that she is expecting.

A tweet from her official account was sent just days after she was seen slumped under a table in a Brazilian nightclub.  It read : "It's official. Pregnant."

The message was posted April 1 to her 5.7 million fans.  Was this an April Fool's Day joke or had her account been hacked?

The posting has been re-tweeted by more than 10,000 users and has become a worldwide trending topic.

Lohan has been dating City Of The Sun guitarist Avi Snow for the past few weeks.

Last week, she was in San Paulo, Brazil to open a new fashion store.

At any rate, Lohan will spend 90 days in a lock-down rehab clinic where she will be treated for alcohol and prescription drug addiction.
