The Jonas Brothers were on MTV’s TRL on Wednesday to promote their new album, "A Little Bit Longer."

NickjonasNaturally, a fan asked what they looked for in a dream girlfriend.

They didn’t offer specifics about blond, brunett, tall or short.

But Joe Jonas said, "If they are nagging and annoying, you’re like, ‘Go away,’ "

And older bro Kevin Jonas agreed. "We’re not ever really with people, ’cause we’re always traveling. And you get on the phone and they’re like, ‘My day is awful, blah,’ and you’re like, ‘This is not what I need right now!’

But Nick Jonas, who used to date Miley Cyrus and is currently dating Selena Gomez, was all about the Mom Factor.

"They have to be good to their moms," said the 15-year-old. Sweeeeeet.
