Megan Fox has sparked more speculation that she's pregnant after being pictured on holiday with husband Brian Austin Green.

The Transformers star, 26, has been snapped with Brian, 38, kissing his bikini-clad wife's belly.

Megan - who stars in new comedy Friends With Kids - and her actor husband were snapped looking happy and affectionate during a relaxing break on the Hawaiian island of Kona.

The pair married in Hawaii in July 2010, with Cassius, Brian's son from a previous relationship, as the only guest.

Last month Brian brushed off rumours that his wife was pregnant.

"They've been saying that every three months ever since we got married, and it's sort of one of those things that they love to say," he told
