Legendary guitarist Slash (VELVET REVOLVER, GUNS N' ROSES) performed at the opening party for actor Charlie Sheen's new bar, El Ganzo (The Goose), on December 28 in the Mexican resort area of Los Cabos. Also appearing at the event were Los Angeles mayor Antonio Villaraigosa and "The Biggest Loser"'s Dr. Robert Huizenga.

Video footage of Slash's performance can be seen below.

During his introduction of Slash, Charlie yelled out, "How we doing? ... Lying bunch of f**got a**holes, HOW WE DOING?"

Charlie later expressed regret saying, "I meant no ill will and intended to hurt no one. I apologize if I offended anyone." He then added, "I meant to say maggot but I have a lisp."

Sheen, a neighbor and personal friend of Slash's who called himself a "Rock Star From Mars" when he underwent a public meltdown amid his firing from the CBS show "Two And A Half Men", spoke at Slash's Hollywood Walk Of Fame induction ceremony in July. He said, "It's quite fitting that Slash is getting a star on the very street Axl Rose will one day be sleeping on."

He added, "This star is going to be stepped on more than the coke we did in the '80s."

In an interview with Australia's long-running rock station Triple M during his tour with the Soundwave rock festival in March 2011, Slash spoke about the troubles Sheen was facing at the time.

"I love Charlie," Slash smiled. "Charlie is probably the most rock 'n' roll character in entertainment today. All things considered, he's been having a little bit of a hard time recently with all the bad press and everything. But he's been managing to get away with what he's been doing on that show and get a raise over the last more than ten years. I think that's pretty cool," he laughed.
