Joanna Krupa and Derek Hough do the Lambada on Dancing With the Stars.

The weekend is already underway, so let’s get straight to it:

The electro-hop group LMFAO will do double duty tonight, first with a show at the House of Blues at Mandalay Bay, then a hosting gig at The Bank at the Bellagio.

Stunning supermodel and “Dancing with the Stars” contestant Joanna Krupa follows and will be at Jet at the Mirage this evening, while Jay Leno returns to the Terry Fator Theatre for another two-night stand, tonight and tomorrow.

LeAnn Rimes is back in town this weekend, too, and will be next door from Leno tonight, performing at Treasure Island.

Kelly Clarkson, the Veronicas and Parachute will all be at the Hard Rock Hotel and Casino this evening, as Clarkson’s "All I Ever Wanted Tour" rolls through The Joint.

Also taking to the Friday night stage in Las Vegas is R. Kelly, who will host an after-party at Hawaiian Tropic Zone following his concert at Planet Hollywood.

Also at PH tonight, Privé’s new resident night DJ, Jermaine Dupri, will mix business with business -- and, yes, a little pleasure -- as he toasts the launch of his new watch line, Nu Pop Movement.

The weekend will continue on Saturday as Tony Hawk brings his “Stand Up for Skateparks” tour to the Wynn.

The resort has transformed its pool area for the extreme event, which will feature a performance by legendary punk rockers Rancid.

Among those expected to attend, in addition to Hawk himself, are Vegas-based tennis pro Andre Agassi; soccer pro Mia Hamm; hip-hop icon Sean “Diddy” Combs; comedian David Spade; and actress Jamie Lee Curtis.

Later Saturday night, Ms. Nevada 2009, Georgina Vaughan, will be at Privé to host the official afterparty for the Ms. Nevada USA pageant.

And as the pageant action winds down at PH, things will just be heating up at the new Hard Rock Café on the Strip as the latest incarnation of Everclear takes to the stage, along with openers Clayton Senne and Theory of Flight.

And finally, John Fogerty rounds out the Saturday night line-up, and will perform out in Primm.

Sunday’s main celeb event will go down at the Rio, where Motley Crue rocker Vince Neil’s charity poker tournament, will take place.

Among those expected to take to the tables is comedian Vinny Favorito.

Aside from that, the line-up is pretty low-key: The usual star-studded brunch crowd is expected at Simon at Palms Place, and Low vs. Diamond will play Wasted Space at the Hard Rock.
