Cody Simpson Shows Off Biceps For Charity

My, how they grow. Like his American clone, Justin Bieber, 18, the Australian answer to every young girl's prayers, Cody Simpson, 15, went with the muscle-shirt look at his Nevada Wild Fest performance, which will benefit the LIli Claire Foundation, at the Rio All Suite Hotel and Casino in Las Vegas.

Simpson and Bieber aren't oblivious to the comparisons made between them. In fact, they've embraced them, with Simpson teaming up with Bieber for certain performances on his Believe tour.

"Chicago shows tonight and tomorrow with @justinbieber," Simpson tweeted earlier this week before taking the stage with the Biebs.

And that's not all. Cody reportedly wants Bieber and his girlfriend, Selena Gomez, 20, to hang out with him and his not-quite-girlfriend, Kylie Jenner, reports Hollywood Life. "It’s awesome because the fans are beginning to see that we’re like a family almost; we’re all supporting each other. We’re a young dream team.” He also adores the Kardashians, Jenner's step-family — especially their constant press and tweeting about him, talking about how much he appreciates the "support of such a famous family."

Simpson will also join Bieber for the November leg of his tour. "Selena visits often and she's cool to chill with. Me and Justin like to do teenage stuff — we recently visited a haunted house which was so cool!” Simpson told the magazine.
