Lorde – 18. There's heaps of pop stars who'll be celebrating landmark birthdays this year, starting off with New Zealand singer-songwriter Lorde. The 'Royals' singer has blown up over the past 12 months, with everyone going head-over-heels for her debut album 'Pure Heroine'.
Avril Lavigne – 30. It seems like only yesterday that a teenage Avril caused sales of stripy tights to skyrocket with the success of single 'Complicated'. This September, she'll be 30, and presumably spending her birthday with husband Chad Kroeger of Nickelback fame. There's a lesson, kids: life always disappoints in the end.
Katy Perry – 30. Joining Avril in the turning 30 club is faux-lesbian titillation expert Katy Perry. She released her last studio album 'Prism' in 2013.
Kid Cudi – 30. The US rapper and pal of Kanye West celebrated his 30th birthday in January of this year. Despite his tender years, he's already achieved the ultimate goal: he's head of his own record label which has the best name ever, Wicked Awesome Records.
Tom Morello – 50. Rage Against The Machine guitarist Morello turns 50 this May, although maybe he's getting a bit mellower nowadays – he's recently landed a touring gig playing live with esteemed rock elder statesman Bruce Springsteen, for starters.
Chris Cornell – 50. Soundgarden frontman Chris Cornell will have been around for a half-century this year. The band will be playing their classic LP 'Superunknown' at SXSW tomorrow, while the singer's allegedly been receiving a spate of nasty death threats on Twitter from an obsessed fan.
Mark Lanegan – 50. Former grunge mainstay with his band Screaming Trees, Mark Lanegan released his eighth studio album 'Imitations' last year and also found time to work with old pal Josh Homme on Queens Of The Stone Age's '...Like Clockwork', too.
DMC – 50. Darryl 'DMC' McDaniels will celebrate his 50th birthday on May 31. A member of hip hop innovators Run DMC, he's also released a handful of solo records and continues to be deeply involved with charity work in the US.
Eddie Vedder – 50. Courtney Love isn't the only grunge icon turning 50 this year. Pearl Jam man Eddie Vedder will also be celebrating half-a-century in the game – he and his bandmates released their long-awaited new album 'Lightning Bolt' last year, following on from Vedder's 2011 solo LP 'Ukelele Songs'.
Jimmy Page – 70. Page is now 70 years old – which, incidentally, is how long it feels he's been surrounded by 'will-they-won't-they' whispers about a reunion with his old bandmates. Their live film 'Celebration Day' sparked fresh rumours the classic rock band would reform, but there's been no fresh developments as of yet.
Roger Daltrey – 70. The man who once claimed he'd rather be dead than embrace old age has just turned 70 years old. And he's showing no signs of letting up, either – he's responsible for curating this months' Teenage Cancer Trust gigs and also says The Who will be making a new album this year to celebrate their 50th anniversary.
Jeff Beck – 70. Guitar supremo Jeff Beck will celebrate his 70th birthday in June 2014. Regularly acknowledged as one of the greatest guitarists of all time, releasing a load of solo albums and also recording with the likes of Mick Jagger, Kate Bush and Morrissey.
