Despite the recent tumultuous relationship between Joe Jonas and his two brothers Nick and Kevin Jonas which led the band to cancel its U.S. tour recently, Joe looked cool and calm as he stepped out and even chatted with ex-girlfriend Camilla Belle at the Wallis Annenberg Center for the Performing Arts Inaugural Gala on Thursday, Oct. 17.

Speaking to People Magazine at the event, Joe remained quiet when asked about the future of The Jonas Brothers but hinted that he may be moving onto acting.

"I think acting would be fun," Jonas said. "I would like to [get into that]."

When he was asked about the conflicts within the band, he said: 'I'm not going to talk about that right now.'

He wore a black tuxedo, white shirt and bow tie at the Beverly Hills event. Inside, he stopped to chat with ex-girlfriend Belle whom he dated in 2008 after he broke up with Taylor Swift. Belle and Jonas broke up in July 2009.

Belle looked stunning in a light pink-cream, Salvatore Ferragamo gown with plunging neckline, Perez Hilton reported. She had a bronze tan, smokey eyes and her dark hair was pulled into a slick hair bun. After he chatted with the 27-year-old star, Jonas took a seat next to Glee star Chord Overstreet to enjoy the night's performances.

Jonas seemed calm despite the reports that surfaced on Wednesday, Oct. 16, in which it was alleged that he has been struggling with a "secret drug addiction."

The rumors alleged that his "secret drug addiction' was the real reason why the Jonas Brothers cancelled their tour last week, according to Star Magazine.

"He's [Joe] been dealing with substance abuse issues for quite some time,' a source told Star. However, the band officially claimed the cancellation was the result of "creative differences."

Meanwhile, TMZ reported that Jonas has been spending a lot of time with sober living coach Mike Bayer, who was the one who helped Demi Lovato get through her abuse problems as well. Bayer is the CEO and founder of Cast Recovery Services. Hollywood Life reported that Jonas was spotted with Bayer on Oct. 10.
