The Take That singer has been invited over to the monarch`s royal residence, Buckingham Palace in London, for discussions about whether he can arrange lavish events for Elizabeth`s 85th birthday on April 21 next year and her Diamond Jubilee celebrations in 2012. A source told The Sun newspaper: "Her Majesty has been made well aware of Gary`s charity work and the events he has put together. "Gary`s got the power to pull in some big names and ensure it`s a party to match the occasion. The timing means he can get the ball rolling early and start ringing his contacts." The queen`s advisers have apparently approached the 39-year-old singer/songwriter because of the outstanding celebrity bashes he has arranged in the past. Last year he persuaded a group of stars - including Cheryl Cole and Kimberley Walsh - to climb Mount Kilimanjaro for charity and also helped raise over £2.1 million by organising the Children In Need Rocks concert at London`s Royal Albert Hall.
