Claim to fame: 98 Degrees singer, Nick Lachey's younger brother
Last seen on: Season 2 in 2006
Standout moment: The former pop star and partner Cheryl Burke outlasted pro wrestler Stacy Keibler, thought to be the favored finalist, along with NFL great Jerry Rice. Lachey and Burke received their first perfect score from the judges in Week 6 of the competition, for their tango to "Shut Up." They received two more perfect scores in later weeks.
Week 3 All-Star elimination:This double-elimination episode sent home not one but two former "DWTS" champs. Lachey's "Crazy In Love" cha-cha with partner Anna Trebunskaya earned the couple 24 points from the judges. But the Season 2 champion couldn't quite get his foothold in the competition and found himself in jeopardy in the first week. Despite his best efforts to show his chest and bare his b-boy skills, he suffered from performing first in the competition. | RecapAdam Larkey / Associated Press
