Def Leppard are in Dublin, Ireland, where they're starting work on a new album.

Guitarist Vivian Campbell says, "We're putting in about four to five weeks here total, and then we'll get together again in May and do another three weeks or so. It will be probably next year before it's all done." When completed and released, it will be their first studio album since 2008's Songs From the Sparkle Lounge.

Def Lep just released a deluxe version of their 1996 album, Slang, and they plan to tour this summer.
