The Jonas Brothers took to their Twitter to wish Miley Cyrus a happy 17th birthday-- they even used her nickname, Miles.
Hmm -- guess there's no bad blood between Nick and his ex-GF, Miley! Remember, Miley and Nick got back together this summer, but then broke up again. She's rumored to be dating her The Last Song costar Liam Hemsworth.
Is it weird to wish your ex a happy birthday? Are you glad that Nick and Miley are still friends?
