"Dancing with the Stars": Finalists compete for mirror ball trophy

In the final two-hour performance show, the remaining couples competed in three rounds of dance.

It's down the wire on season 16 of "Dancing with the Stars," as thefinal four pairs each performed three routines Monday night.

Kellie Pickler probably couldn't have said it better: "Four couples left and everyone is amazing." Jacoby Jones said at the top of the show, "At the end of the day, it's about getting that mirror ball trophy,"

But on Monday, some contenders fared a little better than others. Only one couple will walk away with the coveted mirror ball trophy when the winner is announced Tuesday night. It's down to celebrity contenders Pickler, Jones, Alexandra Raisman and Zendaya.

"Dancing with the Stars" host Tom Bergeron brought up the emotional level on Monday when he made mention of the Oklahoma tornado tragedy: "Here's why. We're a live show, and as such, occasionally we go to air in the shadow of tragic events. That happened April 15, when we went to air hours after the Boston bombing. And it's happened again today. While we're having a celebration here [in the ballroom], we want you to know our thoughts are with everyone who's been affected by the devastating tornado in Oklahoma City."

As for the competition, Zendaya and Pickler both had two rounds of perfect 10s. Raisman received perfect scores on her freestyle, but not her first dance. The judges also praised Jacoby Jones. But the Baltimore Ravens' star fell short of the rest on his dances.

The pairs performed three routines: the judges' pick, a cha-cha relay round and freestyle. Jones and Karina Smirnoff kicked the night off with an energetic, but somewhat sloppy performance, according to the judges. Len Goodman said they have definitely improved, but noted "you got excited at times and lost it." Carrie Ann Inaba echoed Goodman's sentiment as the night rolled on, telling the duo, "I want you to be the star, but I feel like it got a little bit lost in the shuffle."

Raisman and Mark Ballas showed off their moves with samba routine, scoring 28 out of 30. Goodman described the dance as "fantastic." At one point in the night, Goodman said, "I'm dubbing you Alexandra the great!"

Pickler and Derek Hough started their night with a quickstep, which Inaba said was "was really fantastic." They ended up with 30 points for that routine.

With those high scores, it's really a toss-up at this point, but it looks like it will come down between Zendaya and Pickler. Still, Raisman has also been rising steadily. Viewers' votes will be tallied, and the top three couples will perform a new routine in an "Instant Dance" to help decide the winner on Tuesday night. The rest of this season's celebrity contenders will return for the season finale, which will also feature performances by Pitbull, Wynonna Judd, PSY and Jessica Sanchez.
