Joe Jonas declined to comment on the recent rift that has thrown the future of family band The Jonas Brothers into doubt.
The trio - comprised of Joe, Kevin and Nick Joans - scrapped their entire tour just a couple of days before it was due to start, with a publicist citing a "deep rift" as the reason.
The star attended the inaugral gala for the new Wallis Annenberg Centre for the Performing Arts in Beverly Hills when reporters probed him with the inevitable questions about his current relationship with his siblings.
"I'm not going to talk about that right now," he said.

Joe has also had to bat away rumours that he is battling a drug addiction - an allegation that was quickly being touted as a reason behind the JoBro's apparent split.
He did, however, say he wants to break into acting, reasoning that it "would be fun". He has already appeared in US sitcom Hot In Cleveland, as well as the two Camp Rock movies alongside Demi Lovato.
At the same event he also came face-to-face with ex-girlfriend Calilla Belle, four years on from their 2009 split.
The beautiful brunette looked stunning as she posed for pictures ahead of the bash, in a sheer nude dress that must've reminded Joe exactly why he fell for the actress in the first place.
The couple must be on friendly terms though as, according to E! Online, Camilla went over to Joe during the night to say a quick hi. How nice.
