Jimmy Kimmel made Nick Jonas noticeably uncomfortable during an interview on 'Jimmy Kimmel Live' (weeknights, 12:05AM ET on ABC), joking that his solo album spells an inevitable breakup of the Jonas Brothers, and questioning the state of Kevin Jonas' virginity now that he's married long-time girlfriend Danielle Deleasa.

Jonas said that his solo album, 'Who I Am,' came about because he'd written a batch of songs that didn't fit stylistically with the Jonas Brothers.

Watch the video after the jump.

He may not have recently exchanged an "I do" like his older brother Kevin, but Nick Jonas has a new relationship of his own to crow about, and he'll do it as guest host of 'Live with Regis and Kelly' come January.

According to Just Jared, Jonas will be subbed in for Regis Philbin on Fri., Jan. 8 -- six days after an opening tour begins for Nick Jonas and the Administration, the 17-year-old musician's new band. On Jan. 2, the band will play in Dallas; their first CD, titled 'Who I Am,' is set to be released on Tue., Feb. 2.

Happy 17th Birthday, Miley Cyrus! When this megastar blows out the candles on her cake today, will she wish for:

A Porsche? Nah, got that already.

A kiss from Nick Jonas? Been there.

(S34E16) It was pretty obvious there was going to be at least two sketches with the Jonas Brothers. I called it! I mean, no one apart from the people in my apartment know I called it, but that doesn't change the facts or my sad sense of accomplishment. I had to tune out once they started singing (sorry, 15 year-old girls), but their skits were all right. Alec Baldwin did a fine job of hosting as well, though there weren't any particularly striking sketches. I suppose after doing something like "Schwetty Balls", just about everything else will pale in comparison.
