However, the couple's representative denied knowledge when asked if Holmes was pregnant, saying: "Not that we are aware of".

In other news . The 'Mission: Impossible' actor has hired a team of babysitters to help his fiancée Katie Holmes so she has more time to get in shape for their wedding.
Tom has been joining Katie on her grueling training sessions, and has had to draft in an army of babysitters to look after their baby daughter, Suri, and his two adopted children, Isabella and Connor, when they stay over, so they can exercise without interruptions.
According to TMZ.com, Tom, 44, is "very concerned" that Katie loses the weight she gained while pregnant before their big day.
The actor is said to be willing to do whatever it takes to ensure his future wife looks perfect when she walks down the aisle.
A source said: "Katie has lost a lot of weight - a lot. I've heard that Tom was eager to get her back in shape. Looks like she made him happy - and then some."
Meanwhile, Katie, 27, has reportedly developed a fondness for pumping iron.
Since giving birth in April, she has been lifting weights five times a week to build up her back and shoulder muscles.
The 'Batman Begins' actress has also signed up for the Buff Brides fitness programme, to ensure she regains her toned physique for the wedding - rumoured to be taking place before the end of this year.
