Kevin Jonas — who got engaged to girlfriend Danielle Deleasa in July — will get married this weekend. The Jonas Brothers singer is said to marry Danielle  on Saturday (December 19) in front of family and friends at an estate in Long Island, New York.

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.

“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,” a source said.

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.

“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 honor,” he said.

The 22-year-old musician is reportedly taking part in a wedding rehearsal today (December 18) which features a roller skating rink.
