Rap star Jay-Z is looking to add another string to his bow by organizing the wedding of British pop star Robbie Williams in 2010. The rapper already has a host of businesses that he has made a success but could wedding planning be the next business opportunity that nets the star further millions?

Though Robbie Williams has not confirmed that he actually intends to wed longtime girlfriend Ayda Field, rapper Jay-Z has offered his planning services for their potential union. The artist behind “Empire State of Mind” also offered to perform at the wedding.

At the party on the Caribbean island of St. Barts, Beyonce performed five songs at the Nikki Beach club in her trademark black leotard. Also gathered at the event were the singer’s husband Jay-Z, Usher, Lindsey Lohan and Microsoft founder Paul Allen. It is not known how much Beyonce earned for the performance, but Fox News reports that last year Mariah Carey took home a cool million after performing at the same club last year.

One tourist, DJ Sam Young, took to his Twitter page to announce his surprise at the spectacle, writing: “Jigga, Beyonce & Usher were @ Nikki Beach performing for [Gaddafi] family, WTF?”Beyonce had a very eventful 2009. She was banned from Malaysia for being too raunchy. She also had a sell out Las Vegas show and is now in talks with a major Las Vegas hotel to do a residency that will see the star net millions of pounds for the run.

“I don’t know what Robbie’s entertainment plans are,” he added, “but, as a wedding present, I would get up after the speeches and do a little set.” Rumors were once again reignited that Williams and Field were engaged when the American actress was seen wearing a huge diamond ring on the appropriate finger. Williams’ possible fianc was spotted in the ring during the celebrity England vs Scotland football game in Los Angeles, in which the former Take That singer was participating. According to The Sun, Williams popped the question for real on December 29 at his home in Hollywood. He’d proposed to Field on live radio back in November, but later retracted, saying it had been a joke.
