'American Idol' season 16, episode 10 recap and performances
American Idol/YouTube

"American Idol" turned up the star power on Monday, as 12 of the Top 24 contestants performed celebrity duets to determine which of them would move on. Judges Lionel Richie, Katy Perry and Luke Bryan could only choose seven of the "American Idol" season 16 hopefuls, so who did they pick? Here are the highlights music fans need to see from Monday's episode:

1) Pat Monahan almost steals the show

Train lead singer Pat Monahan arrived to perform not one but two celebrity duets, and he nearly stole the show in both of them. He and Michael J. Woodard performed a rollicking rendition of Train's single "Angel in Blue Jeans" that you can watch by playing the video above; it was bursting with personality, and helped Woodard make it into the Top 14. Monahan was equally entertaining when he covered "Drive By" with Kay Kay, but that duet resulted in an elimination. Still, Monahan's appearance on "American Idol" was a great advertisement for why music fans should see Train live. Does any lead singer have as much fun as this guy does?

2) Michelle Sussett gets sultry

Michelle Sussett was paired with Luis Fonsi, and their choice of song was a surprising one. But their rendition of "I Can't Make You Love Me" pushed both singers outside of the box, and helped send Michelle on to next week. It speaks to how magic can happen on singing competitions if an artist is willing to step out of their lane. Fonsi also had a chance to perform "Despacito" with Brandon Diaz; unfortunately Brandon was eliminated, but the performance was a hit with fans anyway, racking up over 68,000 views on YouTube thus far.

3) Yes, Catie Turner was that good again

Catie Turner and Andy Grammer teamed up in Monday's episode, and given Catie's track record, the expectations were set high for her celebrity duet. Their version of "Good To Be Alive" was everything that it needed to be: big, entertaining and showcasing great chemistry for two artists who'd never performed together before. It was no surprise that Catie is in the Top 14. The fans clearly agree with the judges' enthusiasm for Catie; after this episode ended on the West Coast, her performance was the most-viewed on the "Idol" YouTube channel by a mile, with more than 101,000 views already.
