Kevin Jonas and longtime girlfriend Danielle Deleasa are tying the knot this weekend, according to E! News
The eldest member of the Jonas Brothers will wed Deleasa Saturday in an extravagant wedding at Long Island's Oheka Castle. The family-run, French chateau-inspired venue also hosted the wedding of 'N Sync's Joey Fatone.
Jonas, 22, proposed to Deleasa, a 23-year-old former hairdresser, in July at her New Jersey home with a cushion-cut diamond ring he designed with Jacob & Co.
