Joe Jonas is officially on Team Coco, at least for one night. Jonas rocked 'Conan' last night with a performance of his current single, 'Just in Love.' Jonas and his band delivered a lively version of the track, with electric guitar flourishes and a slower intro section added to the arrangement.

Jonas appeared confident as he sang the lyrics about a relationship in trouble: "When I tell you I would never leave you, do you hear what I say? / Don't understand you, you say you need time, but you've been calling all day / We talk love and they say it sounds crazy / Love's even more wild when you're angry / I don't understand why you wanna change it / Girl, listen to me."

Jonas' solo debut 'Fastlife' only got to No. 15 in its first week of release, but it looks as though the recent MTV O Award winner is going to continue to work his butt off promoting it.
