Mario Lopez is getting pretty good at this pageant stuff. The Dancing with the Stars
hunk is coming back for a third round as host of the Miss Teen USA pageant in Pasadena, Calif., on Aug. 24.
Lopez, who's also handled tiara duties for Miss USA and Miss America, will be joined at this year's pageant by a pair of performers – singer Kat DeLuna and the Jonas Brothers, organizers tell PEOPLE.
The Donald Trump-owned pageant will crown a new winner to take over for Katie Blair, the 2006 champ who sparked controversy last year over her behavior with Miss USA Tara Conner. Despite allegations of improper conduct and partying
, both were allowed to keep their crowns and serve out their years.
The pageant will air live on NBC Aug. 24 at 8 p.m. ET/PT from the Pasadena Civic Auditorium.
