"Coleen wants her wedding to Wayne to be spectacular, so her star-studded 350-guest birthday bash will give her a taste of what to expect when planning the wedding," a source revealed to the magazine.

Her birthday party this week, which is apparently being held at the plush Thornton Manor in Cheshire, will have a circus theme - complete with acrobats and other performers.

And rap star P Diddy and the Sugababes will reportedly entertain Coleen’s guests, who are thought to include plenty of footballers, the Beckhams and former Atomic Kittens Natasha Hamilton and Liz McClarnon.

Wayne and Coleen ’to wed next year’ - Mar 19 2007
Wayne Rooney is "likely" to marry his childhood sweetheart Coleen McLoughlin next summer, sources have revealed.

The England international is set to tie the knot with his long-term girlfriend in the summer of 2008.

No precise date has yet been fixed but the nuptials are likely to have to work around the national team’s fixtures in the Euro 2008 tournament.

The news follows the completion of a £1.5m deal with Hello! magazine earlier this month to exclusively cover the couple’s big day.

The staggering figure is thought to be the largest ever paid by a celebrity magazine to cover a wedding.

Contracts were completed around three weeks ago and the enormous sum also includes exclusive access to Coleen’s 21st birthday party to be held in the Wirral later this month. Both bashes will be lavish affairs with stringent security for the couple and their showbiz guests.

Details of Coleen’s birthday, expected to be held at Thornton Hall in two weeks’ time, emerged in the national press earlier this month.

The couple met in 1998 and began dating in 2001 when Coleen was only 14-years-old. Rooney is rumoured to have proposed to her on the forecourt of a petrol station in 2003.

Sources close to the striker said: "It’s likely the wedding will be next summer although a definite date has not been arranged yet."

Rooney’s agent Ian Monk said: "No date has been set for the wedding and it certainly would not be before summer 2008."

Wayne’s fashion tips - Mar 7 2007
Coleen McLoughlin has admitted she asks fiance Wayne Rooney for fashion tips - despite the fact he knows nothing about clothes.

The WAG told New! magazine the footballer - who has been nicknamed "Scruff" - gives it to her straight when it comes to her outfits.

"I do ask Wayne’s opinion on clothes but he’s not very good at it. He will say if he doesn’t like something though," she says.

But Coleen might soon have more to think about than her look - she’s apparently admitted she’s keen to swap her shopping bags for dancing shoes for a stint on Strictly Come Dancing.

She has been swamped with offers to appear on the latest string of reality shows but says Strictly is the only one she would consider.

She told the Daily Star: "I do enjoy watching TV shows, but the only one I’d consider doing is Strictly Come Dancing.

"I also love I’m A Celebrity but I don’t know how I’d cope in the jungle. I would get ripped apart on X Factor - I can’t sing to save my life."
