KEVIN JONAS celebrated his engagement to DANIELLE DELEASA with a family party in Los Angeles on Saturday night (04Ju09).
Jonas, who proposed to Deleasa on Wednesday morning (01Jul09), invited family and friends to toast the good news with a reception at the couple's favourite L.A. pizza parlour.
The pair, both 21, welcomed 30 guests to the event including the star's brothers and bandmates Nick and Joe.
And Deleasa was able to show off her stunning $75,000 (£51,000) diamond ring, which was created by luxury jewellers Jacob & Co.
Angela Arabo, Jacob's wife, reveals she worked with Jonas to design the perfect ring for Deleasa.
She tells Radar Online, "It was such a pleasure to collaborate with Kevin and create the perfect engagement ring for him. He and Danielle are truly in love and we're so happy for the two of them."
