For George Lopez, 50 is more than just a number, it's the inspiration for a book and a whole new set of jokes.

"You just say '50,' and people react like a bad smell just blew in," says Lopez, who is now 52.

The comedian-actor, who appears 8 p.m. Saturday, May 18, at the Borgata Hotel Casino & Spa in Atlantic City, has made hitting the half-century mark the focus of his latest book, "I'm Not Gonna Lie: And Other Lies You Tell When You Turn 50" (Celebra).

"In my late 40s, I realized I didn't want to turn 50," he says, during a recent appearance on NBC's "Today." "I looked at friends who turned 50 –– they looked like guys you asked permission to go out –– they looked old."

Besides adding about 20 different moisturizers to his regimen, Lopez has tried to keep up appearances by dressing younger than his years. Still, he's been tempted to go the route of the commander-in-chief and own his lack of sartorial hipness.

"Barack Obama rocks the mom jeans - they're not form-fitting, they're really high in the waist," he says on "Today." "But if I'm going to go, I'm going to wear maternity jeans, so I have the panel that stretches –– they have the 'Baby on Board' sign on the back."

Actually, life seems pretty good for Lopez, who recently inked a deal for a new sitcom on FX about a divorced working class Mexican-American dad and successful business owner who is trying to give back by teaching history at night school once a week. FX has committed to air 10 episodes of "Saint George," but will green light another 90 if the show hits certain audience marks, according to EntertainmentWeekly.com

"I'm excited about my new show, couldn't think a better group of people or better place to create than FX," Lopez tells EW. "Now to get ready ... back to Pilates!"

A TV regular for much of the past decade, Lopez hosted Fox's reality dating series "Take Me Out" last summer, and he also unveiled his third stand-up special for HBO.

His "George Lopez" sitcom, which ran for six seasons on ABC, continues in syndication and on Nick at Nite. He also had a two-year run in late-night TV as the host of TBS' "Lopez Tonight."

Of the latter, he tells The Associated Press, "I tried to create a party, and we did. The greatest was getting a harmonica from John Popper and then doing shots with the band, Blues Traveler, in the back."

Still, Lopez is almost relieved that the party's over, "just for the fact that I wanted to live a little bit longer. We went hard every night," he tells the AP. "We did it like the old days. You'd sit around and drink 'til like 11 and then go home and come back and do it all over again."

In the last few years, he also has done voice roles for "Smurfs 2" and "Rio 2," and he recently signed to take over hosting duties from Bill Cosby for the Playboy Jazz Festival, which will be held June 15 and 16 at the Hollywood Bowl.

With so much going on career-wise, Lopez seems to be taking heed of his own advice for new AARP members.

"Enjoy yourself as much as you can," he says on "Today." "Do everything you want to do now, and have a great time. When the time comes for Serenities and protective garments, you won't have any regrets."
