The pair are in regular contact

Kate Middleton and actress Reese Witherspoon are believed to have become pals after meeting at a reception in Hollywood last month.

The Duchess of Cambridge is a fan of 35-year-old Reese‘s work and the pair have apparently been e-mailing and calling each other since they both attended the launch of Tusk Trust’s US Patron’s Circle in Santa Barbara.

‘They’re both high-profile women and newlyweds, so they instantly bonded,’ a friend of Reese‘s tells In Touch.

‘Two of Kate‘s favourite movies are Walk The Line and Legally Blonde.’

Kate and husband Prince William, both 29, toured Canada and California last month as part of their Royal duties and really impressed UK TV personality Piers Morgan.

‘They’re the biggest stars in the world, there’s no question,’ Piers, 46, told the Daily Record.

‘They’ve come to Hollywood and are kicking ass.

‘I think Kate‘s completely natural at this sort of thing.

‘I’m sure she’s been coached, but you can be coached a million times and still be hopeless.’
