Unable to take the Dancing heat, Vincent Pastore has bowed out of the competition.
Pastore, best known for playing Big Pussy on The Sopranos, withdrew from the reality show Wednesday after finding the first week of training too rigorous.
"When I initially committed to joining Dancing with the Stars, I didn't realize just how physically demanding it would be for me," the 60-year-old actor said in a statement. "Unable to put forth my best effort, I felt it appropriate to step aside and give someone else the opportunity."
"I'd like to thank ABC and the show's producers for inviting me to participate," he added. "I wish my partner, Edyta, and the other dancers the best of luck."
His partner, Edyta Sliwinska, told E! News' Samantha Harris she was "sad" about Pastore's departure.
"We started to practice and we had two very good practices, but it was just physically too hard for Vincent," she said. "He had a heart operation about a year and a half ago and he put on some weight. He just couldn’t do it. He was too tired."
She did not yet know who would be taking Pastore's place as her partner, but said she was "scared and excited" to find out.
Pastore's short-lived tenure on Dancing wasn't his first experience with reality television. He also appeared as a contestant on the last season of VH1's Celebrity Fit Club, during which he lost 29 pounds.
Apparently, it wasn't enough.
"We're sad that Vincent felt he was unable to continue in the competition, as he would have been great on the show, but we appreciate him standing aside now rather than having to withdraw later," executive producer Conrad Green said in a statement. "Dancing with the Stars. is physically demanding and it pays to know your limits. We respect his decision."
Meanwhile, the first week of dance training proved to be no problem for Paul McCartney's estranged wife, Heather Mills, despite the prosthetic leg she wears as the result of a 1993 motorcycle accident.
In an interview with Extra, Mills addressed the unasked question on many minds, saying it was "very unlikely [her] leg is going to fly off" during dance routines, but admitting it "would be quite funny" if it did.
"I'll have a strap on which I wouldn't normally in every day life," Mills said of her plans to ensure her limb stays attached. (At least, that's what we think she was talking about.)
Mills said she would take criticism from judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli in stride, while acknowledging the competition could prove challenging for her.
"I've got no dancing background and with my leg I can't push it," she said, adding that she was looking at the experience as a much-needed break from her "mad, crazy life."
Given some of the recent events in Mills' life, it's no surprise she's ready to cut loose and shake a leg.
In the months since she and McCartney announced their plans to divorce, Mills has been raked over the coals by the British press and has even complained of receiving death threats.
Last month, Mills' sister lashed out at McCartney in a message posted on Mills' official Website, accusing him of failing to provide adequate security for his soon-to-be ex-wife.
Earlier this month, Mills paid a visit to a police station near her home in Hove, England to discuss unspecified issues believed to relate to her concerns about personal security.
Because she and McCartney had no prenuptial agreement, Mills stands to walk away from the split with a sizable chunk of the ex-Beatle's $1.6 billion fortune. So far, the couple has yet to reach a settlement.
