Lindsay Lohan: It's official, I'm pregnant

Lindsay Lohan has announced she is pregnant - but it was April Fool's day yesterday.

The star tweeted “It’s official. Pregnant…” which to the UK looked as if she wrote the message on 2 April at 5.35am. However, it was still 1 April on the west coast of America where the star lives.

It is thought to be an April Fool's joke aimed at her fans and her boyfriend Avi Snow, guitarist for City of the Sun.

She was photographed this weekend slumped under a table at a Brazilian nightclub.

The Mean Girls star is also due to enter rehab later this month for prescription drug and alcohol treatment.

LiLo’s potential prank is among a number of April Fools’ jokes pulled by celebrities on Twitter yesterday.

Actress Sheridan Smith tweeted she had been cast as Anastasia Steele in the forthcoming film of Fifty Shades of Grey, and Tom Daley tweeted a picture of his new micro pig.
