Lindsay Lohan with a bulging baby bump

Lindsay Lohan is always full of surprises - a lesbian lover her most notable of late - and she was once again raising eyebrows as she stepped out in LA with a bulging baby bump.

But far from being yet another bizarre installment in her drama filled life, the star was simply sporting a prosthetic tummy for her new film, Labor Pains.

Lindsay plays an assistant at a publishing house who pretends to be pregnant in a desperate attempt to keep her nasty boss from firing her.

After a tumultuous 2007, and a series of box office bombs including I Know Who Killed Me and Georgia Rule, the 21-year-old is no doubt hoping this film will mark the beginning of her career revival.

She has been shooting the romantic comedy for two weeks but has still found time to mix business with pleasure.

She has received regular on set visits from her girlfriend, DJ Samantha Ronson.

Despite a public row last weekend, the pair are once again on loving terms, with a source saying: 'Lindsay's never been happier.'
