Ryan Seacrest and the "American Idol" judges are currently in Las Vegas -- where Steven Tyler and Jennifer Lopez definitely added a little Sin City sparkle to their wardrobes.

While Seacrest and Randy Jackson kept it simple with their clothes at a press conference earlier this week, J. Lo added some glitz by wearing a shimmery top and a whole lotta jewelry.

Tyler took his look one step further -- wearing a pair of bedazzled jeans, a flowy, paisley and cheetah print top and some very interesting shoes.

The gang was photographed at the Mirage, where 60 finalists will sing Beatles songs with a live band before being cut down to a group of 40.
