Peaches Geldof and Katie Holmes hit it off

Katie Holmes has befriended Peaches Geldof.

The unlikely friendship came about after the 19-year-old British presenter asked to interview the actress as part of a stint working for New York magazine Nylon.

The pair got on well immediately, with 29-year-old Katie - who has a two-year-old daughter, Suri, with husband Tom Cruise – sharing acting tips with the teen star.

A source revealed: "Peaches went to see Katie in the play 'All My Sons' and sent her a lovely letter asking if she could interview her for Nylon.

"The pair soon hit it off and enjoyed afternoon tea at a suite in the Rivington Hotel. Peaches played with Suri while Katie read through some film scripts.

"Katie gave her some brilliant advice and Peaches says she is genuinely one of the nicest people she's met and Suri is a doll."

It appears Katie's advice is already paying off – Peaches has been asked to audition for the 'Sex and the City' sequel. The source added to Britain's Daily Star newspaper: "She's ecstatic. She's now on Nylon TV and it's been a great showcase for Peaches.

"She's already caught the eye of 'Ugly Betty' producers and now she's on the list to audition for the 'Sex and the City' sequel.

"It's very early days but it shows she's being taken seriously in New York, something she didn't feel she was in London."
