Katy Perry In Tears Following Tupac Appearance At Coachella Festival 2012

The 'Part Of Me' singer reveals how touched she was after the late rapper is brought back to the stage

Katy Perry has revealed she "might have cried" during Dr.Dre and Snoop Dogg's headline set at Coachella Festival last night (15th April) when they brought late rapper Tupac back to the stage in the form of a hologram.

The 'I Kissed A Girl' star is currently attending the music event in California and was in the crowd for the stand out performance which saw Snoop share the stage with the deceased star before Eminem took to the stage.

An emotional Katy tweeted: "I think I might have cried when I saw Tupac. #coachella."

The singer was also pictured attending Calvin Harris' set at the festival which featured an appearance by Rihanna during 'We Found Love' - with the pair sharing a hug as RiRi performed her smash hit single.

Meanwhile, the 'Firework' star is preparing to release her 3D concert movie this summer and recently admitted she took inspiration from Madonna for the big screen feature.
