Adam Lambert will NOT be leading leather-clad men around on a leash for the So You Think You Can Dance finale.

It was just last month that the American Idol runner up did a number at the American Music Awards that shocked viewers. Lambert sang while dragging men wearing collars across the stage using dog leads.

No way, Executive Producer Nigel Lythgoe tells us. Lythgoe made Lambert fully aware that SYTYCD is a family show and promises his performance will be appropriate to that audience. Besides – the EP says – Lambert now regrets the AMA performance that raised those eyebrows.

SYTYCD heads into the finale Tuesday, 8:00 p.m.ET/PT on Fox.
