Slash has confirmed that he will be part of Ace Frehley's next album, which will focus on cover songs.

Frehley, earlier this year, said he was considering doing songs by the Rolling Stones, the Who, Led Zeppelin, the Beatles – and even his old band, Kiss. Frehley said the album will "probably" include new versions of "Cold Gin" and "Parasite." "On Kiss records," he said, "I'm not singing lead. So I'm going to sing lead on them like I do live so there's (studio tracks) out there with me."

Slash, however, mentioned yet another legendary classic rock band: "Had a really fun, live session with Ace Frehley last night, jamming on a Thin Lizzy tune for his new covers album," he said via Twitter. "Good times."

The ex-Guns N' Roses guitarist also posted a photograph of himself with Frehley and other members of the recording team.

Frehley previously referenced Slash as a possible guest, along with Lita Ford and Mike McCready of Pearl Jam – and said he might even approach former Kiss bandmate Gene Simmons. "I think he'd consider it," Frehley said. "I don't know if he'd do it. Maybe (fellow Kiss co-founder) Paul (Stanley) won't let him. Who knows?"

There is no release date as yet for Frehley's new album, which is reportedly due later in 2015 via SPV/Sledgehammer. His most recent studio effort was 2014's well-received Space Invader.
