AceShowbiz - Blur star Alex James has blasted rocking pensioners Led Zeppelin and the Rolling Stones for refusing to act their age, accusing them of trying to be teenagers.

The Parklife bassist, who is also a newspaper columnist and a top cheesemaker, insists he'd prefer to be behind a food counter in a supermarket rather than trying to relive past glories onstage.

"There are rumours of Led Zeppelin getting back together, and nobody really wants to hear their f**king new record, do they?" he asked British newspaper The Mirror. "They want to listen to Stairway to Heaven. How old were they when they did Stairway to Heaven? Like, 20 or something? And how old are they now? They are f**king 70!"

"I'd rather be on a cheese counter than pretending to be a teenager," he added. "At least people want to come in and try my cheese as well as listen to Parklife... I think it's really good that I've got something else to talk about. You have to do it, otherwise you become this weird, grotesque caricature of yourself by the time you get old, like Mick Jagger."

James admits he's a fan of the Stones, but "wouldn't f**king go and listen to them live", adding, "You can't be Jumping Jack when you are seventy-f**king-eight."

The outspoken star also turned on R&B star Kelis for refusing to perform her 2003 hit Milkshake at the Big Feastival, an event he hosts at his farm in England, in 2014.

"She's like, 'Oh, I don't do that anymore!'" he recalled. "It's like, 'For f**k's sake, it's not like you've got loads of hits, darling! You need to do that one.'"
