Nick Lachey is competing on Season 25 of ABC's Dancing with the Stars this fall.

Nick is a TV personality and recording artist who is married to fellow Dancing with the Stars contestant Vanessa Lachey.

Nick, the former star of Newlyweds: Nick and Jessica and host of The Sing-Off, is partnered with fan-favorite Dancing with the Stars pro Peta Murgatroyd, which makes the competition even more interesting considering his wife is paired with Peta's husband, Maksim Chmerkovskiy.

When Nick made his Dancing with the Stars debut last week, he and Peta tied for seventh place on the leaderboard with two other couples after receiving 18 out of 30 possible points from the judges for their cha cha routine.

Will Nick turn out to be a triple threat onstage by mastering ballroom dance?
