Ron Artest is a forward for the Los Angeles Lakers, and is known for being eccentric off the court. (He has filed papers to legally change his name to Metta World Peace.) On the basketball court, he is perhaps best known for the November 2004 Pacers-Pistons fight. Artest, a Pacer at the time, rushed into the stands to confront a fan who threw a drink at him, which led to the biggest player-fan fight to date.
Kristin Cavallari found fame with MTV reality programs "Laguna Beach" and "The Hills." She has also appeared on "The Middle" and "CSI: New York." Cavallari was engaged to Chicago Bears player Jay Cutler, but he ended their engagement in July.
Former prosecutor Nancy Grace currently hosts "Nancy Grace" on HLN. She is also the author of mystery thrillers "The Eleventh Victim" and its sequel, "Death on the D-List." Grace is married and has twins.
Rob Kardashian is best known as the brother of Kim, Kourteny and Khloe Kardashian. He appears on several of the family's series of E! shows, including "Keeping Up With the Kardashians" and "Khloe and Lamar." He is the second Kardashian to participate in the show. Kim competed in season seven.
Ricki Lake played Tracy Turnblad in the 1988 film "Hairspray." She has since had a long-running daytime talk show ("Ricki Lake," 1992-2004) and hosted a season of VH1's "Charm School." Lake has also made numerous TV appearances.
J.R. Martinez plays combat vet Brot Monroe on "All My Children." Prior to acting on the soap opera, Martinez was in the Army. He was deployed to Iraq in March 2003, but less than a month after that, his vehicle hit a landmine. Martinez was trapped, and suffered severe burns. In addition to acting, Martinez is a motivational speaker.
Chynna Phillips, the daughter of The Mamas and The Papas' Michelle and John Phillips, is perhaps best known as a member of the '90s pop trio Wilson Phillips, whose debut album sold eight million copies. She has also appeared in several films, including "Caddyshack II" and "Say Anything." She is married to actor Billy Baldwin.
Hope Solo is the goalkeeper for the United States women's national soccer team. She was part of the team that went to the 2011 FIFA Women's World Cup finals, but the U.S. ultimately lost to Japan on a penalty shoot-out after a 2-2 tie.
