15 celebs who were star struck when they met their famous heroes (With Pictures)

5. Katy Perry Meets Britney Spears

It took a movie about little blue creatures to bring the two songstresses together in person, despite the fact that both must travel amongst other pop star elite celebs. Katy Perry reprised her role as Smurfette inSmurfs 2 while Britney Spears had a song on the soundtrack. The two met for the very first time on the blue carpet (yes, there really was a blue carpet instead of a red one) at the premiere of the film. Perry was so excited about meeting her idol, Spears, that she got emotional and began to cry. Both ladies looked beautiful in blue dresses as they had their first face to face meet and greet. Before the two met Katy had excitedly told E! Online all about her excitement and how she couldn’t wait to meet Britney.
