Nation's Tweens In Panic As Last-Resort Jonas Proposes

In a stunning announcement that threatens to topple completely the already devastated global financial markets, a Jonas Brother has announced his engagement. The Jonas in question is eldest brother Kevin, 21, and the lucky lady is Danielle Deleasa, of New Jersey, whom the guitarist met in May 2007 while vacationing with his family in the Bahamas. People has the Jonas! Pure-No-Longer! Exclusive!:

[Kevin surprised Danielle] by showing up at her doorstep in New Jersey early Wednesday morning and dropping down to his knee to ask her to marry him. Presented with a cushion-cut diamond ring that Jonas designed with Jacob & Co., Deleasa couldn't believe what was happening.

Then, "She said yes, yes, yes like 500 times super fast in a row," the oldest of the Jonas Brothers tells PEOPLE exclusively.

Brothers Joe and Nick have already tweeted their good wishes to a congratulatory Twitter community, saying: "Yes it's true. Congrats to Kevin. Dani is such a sweet lady." Luckily, the 140-character limit prevented them from voicing further concerns that Deleasa "better not turn into our Yoko, if you catch our drift, and I think that you do. If not, Google 'The Beatles.' Bros before fian-hos! But seriously, though, Dani's the best! Woo-hoo! The purity curse has been lifted!"
