Rod Stewart's wife PENNY :LANCASTER is set to appear on British TV reality show STRICTLY COME DANCING. If she signs, the former model will have to dance the samba, foxtrot and tango live on TV each week. She will also follow in the footsteps of Stewart's ex-wife Rachel Hunter, who appeared on the U.S. version Dancing With The Stars. A source says, "Penny's a huge fan of the show. Bosses think she'll be the ultimate draw - sexy and a good mover. "Every year producers want to get the best possible names and Penny is right at the top of their list. She's keen to sign so hopefully it's all systems go."
