One additional new dancer will round out Dancing with the Stars' tenth-season professional partner cast: Damian Whitewood, an Australian who has won national ballroom and Latin American style championships.
The 11 celebrity participants -- who were revealed during ABC's Monday night broadcast of The Bachelor: On the Wings of Love's finale -- competing on Dancing with the Stars' tenth season are former Baywatch actress Pamela Anderson, NFL star Chad Ochocinco, former All My Children actor Aiden Turner, ESPN reporter Erin Andrews, former Beverly Hills 90210 actress Shannen Doherty, former Apollo astronaut Buzz Aldrin, actress and comedian Niecy Nash, Pussycat Dolls member Nicole Scherzinger, Olympic figure skater Evan Lysacek, former Jon & Kate Plus 8 star Kate Gosselin, and The Bachelor star Jake Pavelka.
Whitewood will be paired with Anderson.
Ballas, who previously won Dancing with the Stars' eighth season with Shawn Johnson and sixth season with Kristi Yamaguchi, will be partnered with Doherty.
Burke, who won the competition's second season with Drew Lachey and its third season with Emmitt Smith, will compete with Ochocinco.
Andrews will be paired with Chmerkovskiy, who will be participating in his eighth Dancing with the Stars edition.
Aldrin will be competing with Costa, a former fan favorite who participated on Dancing with the Stars' first three seasons before leaving the show because she was pregnant with her first child.
Following its March 22 debut, all eleven tenth-season Dancing with the Stars couples will return for another two-hour performance show on Monday, March 29 at 8PM ET/PT. Home viewers will be able to vote following each episode.
The first live tenth-season results show will then air the following night on March 30, with one couple being eliminated based on a combination of the judges' scores and home viewer votes from both performance episodes.
