Kevin Jonas getting married this weekend

The Jonas Brothers singer - who got engaged to girlfriend Danielle Deleasa in July - is set to marry his fiancee on Saturday (19.12.09) in front of family and friends at an estate in Long Island, New York.

The 22-year-old musician is reportedly taking part in a wedding rehearsal today (18.12.09) which features a roller skating rink.

Kevin, the eldest of the pop siblings, met his fiancee in the Bahamas in 2007 and proposed to former hairdresser Danielle, 22, by turning up at her New Jersey doorstep last June with a ring, breaking teen girls' hearts worldwide.

Danielle is said to be walking up the aisle in a strapless Vera Wang gown and a headpiece by designer Denise Leli.

A source said: "Danielle has gone for a romantic dress and an intricate headpiece with floral details, because when she met Kevin on the beach she was wearing a flower in her hair."

Demi Lovato, who starred with The Jonas Brothers in 'Camp Rock', is one of the celebrity guests expected to attend the ceremony.

Kevin previously revealed both of his brothers, Joe, 20, and Nick, 17, will serve as best men.

He said: "Danielle has an older and a younger sister, so it works out really well. I can have two best men, and she can have two maids of honour."
