Katie Holmes has added to speculation she's pregnant by wearing a baggy jumper to cover her apparently protruding belly.

The wife of Tom Cruise set tongues wagging that she is expecting her second child earlier this week when she stepped out in New York sporting a white figure-hugging top and baggy jeans.

But yesterday, the 29-year-old appeared to be deliberately covering her alleged baby bump with a loose pink top.

Holmes has repeatedly denied rumours of a second pregnancy and has thrown herself back into her acting career after taking time out to raise two-year-old daughter Suri.

The actress appears to be dressing for comfort these days - her staple look more in keeping with that of a mum-on-the-run than a multi-millionaire wife.

The former Dawson's Creek star is gearing up to make her first appearance on Broadway in a production of All My Sons, which opens in October.

She recently wrapped filming a guest appearance as a non-profit attorney in one episode of US television drama Eli Stone.

Holmes also attracted attention this week for yet another hairstyle.

In recent weeks she's tried out a Cagney And Lacey 1980s bob and copied the famous 'Pob', before debuting her new wash-and-go page-boy look.
