Prince Harry's 30th Birthday Plans Revealed

Prince Harry is set to celebrate his 30th birthday with a St Moritz-themed party - that's a ski-themed party to you and me.

To mark the occasion, lavish drawing rooms at Kensington Palace will be transformed into a Swiss ski lodge, complete with white leather sofas and fancy drapes especially for Harry's landmark birthday on 15 September. Think the ski room at Oceana, but more royal.

According to a Daily Express source the theme of choice shows just how much growing up Harry has done since getting naked in Las Vegas. Riiight.

"This is an important birthday for Harry and he's not going to fall out of a club late at night," the insider revealed.

"He's keen to show he's come of age."

It is though that his ex Cressida Bonas was in charge of the celebrations, which will see 30 guests sit down to a slap-up meal at the Palace, until Harry's brother William was forced to take the reins after the pair split earlier this year.

News of his birthday plans comes after the royal has allegedly been back in touch with rumoured love interest Caroline Flack.

It is thought that Harry dated the TV presenter in 2009, shortly after splitting from long-term girlfriend Chelsy Davy, and apparently he likes to keep in touch with his former flames.

"They have been in contact by phone," a source told the Mail on Sunday. "Harry likes to keep in touch with his old girlfriends and he knows Caroline is fun and discreet.

"In fact someone mentioned his name the other day and Caroline got flustered and went bright red."
