Mario Lopez Loses Undies Deal to 'Chorus Line' Co-Star with Bigger Bulges

New York City - A Chorus Line star Mario Lopez has muscle envy over his hunky co-star Nick Adams' bulging assets—Adams' big biceps!

Dancing with the Stars phenom Lopez reportedly pitched a fit when the producers of his latest vehicle, a sexy revival of A Chorus Line, tried to cover his muscle-bound torso with his character Zach's traditional long-sleeve tan sweater.

Bucking Zach's costume since the Tony Award winning show debuted in the '70s, Lopez opted for a short-sleeve brown, bicep-revealing top to show off his "guns."

But beyond the desire to display his own goods, Lopez's jealousy over Adams' hot body came to a head when Lopez demanded the young buck wear a baggy hoodie whenever they danced side by side.

The battle rages on now that men's skivvy company 2(x)ist has picked Adams as the favorite ripped, shirtless, dancing man to front its latest ad campaign, the New York Post's Page Six reported.

"Mario was originally No. 1 on our radar as we planned the campaign," a source told the Post. "We were ready to call him with an offer, but then we saw Nick. He's younger, sexy, more interesting. On top of that, his body was crazy. We set up a meeting, and when he walked in, that was it. We never even looked at anyone else after that."

The ad campaign reveals Adams in an unbuttoned tuxedo shirt, a bow tie and underwear. Look for it to bust out of the pages of Out's August issue first and then in other magazines.

Jason Scarlatti, 2(x)ist's creative director, gave final approval. He told the Post, "Nick's very masculine, sexy, modern. It's totally all about his body. Mario is a good-looking guy, but Nick had it. He's up and coming, the new face of sexy. He's original. He's hot."
