Some thought Katy Perry's hook-up with our own Russell Brand was a joke back in 2009 but no they even got hitched! But after one year of marriage Brand has filed for divorce from the singer.
The pair have decided to move on because they're busy scheudles mean they're just not together enough any more – or at least that's the official line.
To mark their break-up, Gigwise has taken a look at some of the most famous rock star couples from down the years.
From the notorious pairing of Nancy and Sid to Gwen Stefani and Gavin Rossdale, this collection is a must-see and perhaps a warning to any up and coming music couples that not everything lasts forever.
