The Jonas Brothers Celebrate Kevin's Engagement!

As many of us imagine life with only two single Jonas Brothers, Kevin and his fiancée Danielle Deleasa celebrated their engagement with a pizza party in L.A. over the holiday weekend.

The newly engaged couple and Kevin's brothers, Nick and Joe, all gathered along with over 30 of the couple's closest friends and family on Friday (see full picture after the jump), reports Extra. All the partygoers seemed quite happy and were all smiles as they left the Italian restaurant.

Nick and Joe have already been quite public about their excitement for the duo. Shortly after they announced their engagement, they took to Twitter. "Congrats big brother.....Dani welcome to the family," they wrote. "We can't wait to have you join us on the road! Love Joe and Nick."

The couple, who got engaged last Wednesday (July 1), also celebrated their union with a shopping spree in Toronto. The pair hit up Chanel, Louis Vuitton and Holt Renfrew on Saturday.

Of course, as we all know by now, Kevin does have impeccable taste when it comes to style, fashion and buying lovely gifts for Danielle. The eldest Jonas Brother gave Danielle quite the piece of bling when he proposed to her. The 21-year-old helped design the 3-carat solitaire cushion-cut diamond, surrounded by 210 round brilliant-cut pave diamonds along with celebrity jeweler Jacob the Jeweler of Jacob and Co.
