Divo alert: We hear Mario Lopez insisted on some star treatment before a night of partying last weekend at the MGM Grand at Foxwoods.

"He had to get a manicure and pedicure before going out," says a source.
 
While the former "Saved by the Bell" star was happy to do a TV interview before heading to club Shrine, there was one request he wouldn't tolerate.

"The guy first suggested Mario change his shirt, which he was happy to do," says the insider. But the journalist didn't stop there.

"He then insisted that Mario fix his hair before they started rolling, and that really crossed the line. Mario blurted out, 'No! — you're not going anywhere near my hair!'"
