Oops! Joe Jonas appears to have to accidentally spilled the beans about li'l bro Nick and Miley Cyrus getting back together!

Larry King grilled Joe about his love life and the 19-year-old proudly said he does have a girlfriend. Then Larry asked Joe if his GF was as "famous" as Nick's and Joe answered, "I don't think anybody's as famous as Miley Cyrus."

Last week, Miley and Nick were seen jet skiing together on Tybee Island in Savannah, Georgia. The "Hannah Montana" megastar dished in an interview with a Tennessee radio station, "He's my best friend, and we still hang out all the time, and we've definitely reconnected."
