The troubled Sons of Anarchy actor and Katy Perry got together in 2005 and broke up in 2006, before her singing career took off. Lewis died in 2012 in a fall from a roof, and reportedly inspired Katy's hit "The One That Got Away."
Russell Brand, whom Katy Perry was married to from 2010 until December 2011, is the only man she's tied the knot with. It was a coupling that seemed so crazy it just had to work ... until it didn't work, then it just seemed crazy.
The relationship everyone loved to hate produced some actual good times as well as bad during 18 months of makeups and breakups. At least Perry can reflect on happier times with his "Who You Love," featuring Katy, and her own song "It Takes Two," on which Mayer plays guitar.
Robert Pattinson has been linked to Katy Perry more times than we can count in the past year. Have they ever actually dated? Or hooked up? They've clearly hung out a bunch, but the hard evidence is elusive.
