LOS ANGELES — “Dancing With the Stars” unveiled its new ballroom and new cast Monday, and when all the dancing was done, singer Chynna Phillips and actor J.R. Martinez were tied at the top.

Phillips and Martinez each earned 22 points out of 30 for their Viennese waltzes. Basketball star Ron Artest landed in last place with 14 points. Head judge Len Goodman said the Lakers forward’s footwork was “atrocious” and his cha-cha was “all sizzle and no sausage.”

Artest, who recently changed his name to Metta World Peace, had the Hebrew words for “world peace” shaved into his hair for his “Dancing” debut. Despite his low score, he said after the show that he “came to entertain” and felt the judges were fair.

Scoring one point better than Artest was Italian actress Elisabetta Canalis, who is better known in the United States for being George Clooney’s ex-girlfriend. She said her nerves got the better of her in the ballroom and she left the episode worried about tonight’s results show, when the season’s first celebrity contestant will be dismissed.

Judges’ scores are combined with viewer votes to determine who is ousted each week.

Also making their dancing debut on the hit ABC show were World Cup soccer player Hope Solo; reality stars Robert Kardashian and Kristin Cavallari; TV personalities Nancy Grace, Carson Kressley and Ricki Lake; actor David Arquette; and author and activist Chaz Bono.

Kardashian brought his famous family along: Sisters Kim and Khloe, mom Kris Jenner and brother-in-law Lamar Odom sat in the ballroom. The reality star scored 16 points, as did Grace. She said after the show that she hopes to make it through tonight’s elimination episode, but Kardashian said he needs to stay on the show for at least four weeks.

“It’s obvious I need to beat my sister,” he said of former contestant Kim. “She was only on it three weeks.”
