All summer long, in bars and dance clubs and cars with stereos cranked up, it was almost impossible to escape Nelly's refrain, "It's gettin hot in here ... so take off all your clothes."

With any luck, the catchy lyrics were a sign of the temperature at the St. Louis rapper's concert tour, which comes to Washington's MCI Center Saturday.

Armed with a lineup that includes rappers Lil Wayne, Big Tymers and Fabolous, the Nellyville tour looks set to be a hit. Nelly's ubiquitous hits "Hot in Herre" and "Dilemma" alone may be worth the trek.

Warning: No prudes allowed -- just in case fans decide to heed Nelly's saucy lyrics.

Tickets for the concert, which begins at 7 p.m., are $45 and are available at ticketmaster.com or 410-481-SEAT.
