NEW YORK (AP) -- Paula Abdul stopped just short of declaring Adam Lambert the future winner of "American Idol."

Instead, she compared him to a certain Olympic swimmer.

The "Idol" judge praised yet another Lambert performance Tuesday night, telling the 27-year-old actor that each week "it's like watching the Olympics and you're our Michael Phelps."

Indeed, as the popular Fox show winds down to the finale, it seems Lambert is destined for a spot in the showdown to win the title.

Who else will compete to the end?

That's anybody's guess as the other four finalist delivered strong renditions of retro "Rat Pack" standards.

Jamie Foxx a stylish singer himself was the guest mentor.
