It took Joe Jonas a little while to warm up at Beacher’s Madhouse at the Hollywood Roosevelt Hotel, but once he did, the singer had a blast. Jonas arrived at 11:30 p.m. with some guy friends, and was quite amused every time a little person would fly to a table to deliver another bottle. He flirted politely with a few girls who approached his table, and even laughed when Jay-Z’s “On to the Next One” – a song that pokes fun at Jonas and his brothers – came on in the club. After watching the Beacher’s Babies burlesque dancers, he left at closing time.
