Former Miss Alabama Katherine Webb will join the cast of 'Celebrity Diving' on ABC.

ABC announced actress Pamela Anderson, a former contestant from "Dancing With The Stars," was added to their "All Stars" edition for season 15. Anderson sat on a panel at the Television Critics Association conference when the announcement was made with several other contestants from the "All Stars" cast. The 11 other returning celebrity contestants joining Anderson are Bristol Palin, Kelly Monaco, Melissa Rycroft, Shawn Johnson, Kirstie Alley, Joey Fatone, Helio Castroneves, Drew Lachey, Emmitt Smith, Apolo Ohno and Gilles Marini.

"Dancing with the Stars" dancer Cheryl Burke stepped out in West Hollywood with younger actor Zac Efron. Burke, 28, was hanging out with the "High School Musical" star in West Hollywood at Bootsy Bellows. Efron, 24, joined Burke and her group of girls in the VIP room at the popular club. "At one point, they went up to get drinks from the bar, and they showed off their dance moves," an onlooker told PEOPLE exclusively. "They ordered a few cocktails to bring back for them and their friends."

Dancing with the Stars contestants face their first elimination tonight as the show ends its second week of the season.
