LOS ANGELES – “So You Think You Can Dance” producer Nigel Lythgoe won’t say which dancer will end up the winner on Wednesday’s season finale. But he’s confident predicting that guest starAdam Lambert is going to be well-behaved.

Lythgoe said he passed the message to Lambert’s camp that he doesn’t expect any surprises during the live, two-hour episode, airing at 8 p.m. EST on Fox.

Last month, Lambert’s racy performance during the American Music Awards on ABC drew the ire of the network, which contended that he went further than he had during rehearsals. He was dropped by ABC from a “Good Morning America” appearance.

Other singers on the Fox show’s finale include Jennifer Lopez, Mary J. Blige and Leona Lewis, with a performance by the Groovaloos dance group.
