The former bandmates took the plunge to raise awareness about the condition and raise funds for the Als Association after Bon Jovi nominated them to follow his example at the weekend (16-17Aug14), when he recruited New Jersey Governor Chris Christie and New England Patriots owner Robert Kraft to tip an ice bucket over his head at a garden party.
Celebrities have been taking the challenge, filming it, posting the footage online and nominating famous friends to follow suit for weeks, boosting the charity's coffers and raising awareness about Als, aka Lou Gehrig's Disease.
Sambora, who quit Bon Jovi last year (13), took the challenge in his back garden and nominated his reported guitarist girlfriend Orianthi and "friends and fans around the world" to follow his lead, while Gavin DeGraw and Ryan Cabrera were picked by keyboard player Bryan after he was dunked in his swimming pool.
Bon Jovi drummer Tico Torres posted his Ice Bucket Challenge on the band's Facebook page and nominated Alice Cooper, who took the opportunity to cool off on Wednesday (20Aug14) when he was chilled onstage during a concert in Virginia Beach.
He nominated tour co-headliners Motley Crue and movie star pal Johnny Depp to take the plunge. Motley Crue quickly accepted Cooper's challenge with their own onstage dunking, and named Aerosmith, Def Leppard and Kiss to follow suit.
Paul Stanley has already accepted on behalf of Kiss, insisting he'll take on the challenge on Friday (22Aug14).
Cooper is also hoping to raise more money for the Als Association by selling the stars and stripes T-shirt he was wearing when he was iced onstage and the bathrobe he changed into backstage to raise cash for the cause.
