Katie HolmesKatie HolmesStudio bosses must have rejoiced when Katie Holmes arrived at The Pursuit Of Happyness US premiere.

There are not many guests in showbiz who are happier at the mo.

Having just got hitched to Tom Cruise and fresh from her honeymoon, Katie's smile was on full wattage (rumour has it, it caused a power surge in the Westwood, California area).

Not only that, Katie's got their little 'un Suri, as well as Tom's new United Artists contract to get excited about.

So it was pearly whites all round for Katie - and the feeling seemed to be infectious.

The star of the film, Will Smith, couldn't stop grinning and nor could his co-star Thandie Newton and his wife Jada Pinkett Smith.

So catch the sense of warmth and cheer in the gallery above.

NB. Dislikers of cheese need not apply.
