The limos are warming up, hair is being coiffed and makeup applied as bizzers gear up for the last lap of Emmy season.

Making the rounds of pre-Emmy parties on Saturday, Emmycast exec producer Mark Burnett promised that tonight’s three-hour show from the Nokia Theater will be unlike any of the previous 62 Emmy fetes.

“It’s looking a lot like the MTV Video Music Awards,” Burnett said with a mischievous grin Saturday night at theEvening Before before fundraising event in Century City.

Expect a youthful infusion of talent and plenty of stunts that will be talked about into the wee hours of Monday, Burnett added. As for those Internet rumors that Charlie Sheen will be making a surprise appearance on the telecast, Burnett would only say: “You know me. What do you think?”

In a sign that the showbiz economy is on the upswing, Emmy weekend was definitely busier than it has been in the past few years, and the mood among industryites is hopeful.

WME packed ’em in on Friday night at its sprawling party at Milk Studios in Hollywood, which marked the percentery’s first large-scale pre-Emmy bash since WMA and Endeavor tied the knot in 2009. With so many top execs, agents and creatives together under one (spacious) roof, undoubtedly some business got done, or at least started, there.

ICM hosted an intimate gathering Friday on the roof the London West Hollywood (even the balmy weather cooperated). “Modern Family’s” Eric Stonestreet and Jesse Tyler Ferguson had quite the receiving line of fans who wished them well as they go up against each other and fellow co-stars Ty Burrell and Ed O’Neill for supporting comedy actor honors.

Saturday’s soirees included Showtime’s poolside party at Skybar and NBCUniversal’s blow-out at Spago, which served up enough Godiva chocolates to sink a battleship and macarons in every color of the Peacock’s plume (and then some).
