Russell Brand’s kiss with Katy Perry has been dropped from his new movie.

The British funnyman - who reprises his Forgetting Sarah Marshall role of rocker Aldous Snow in Get Him To The Greek - locked lips with his real-life fiancee, who has a cameo in the forthcoming movie, but test audiences were bemused to find the scene had been removed and replaced by a smooch with fellow pop star Christina Aguilera instead.

A source told the Daily Mirror newspaper, “There has been a few early screenings over in the States and Katy wasn’t in it. Everyone had been waiting for the big kiss scene, but it wasn’t there. It’s the moment the big romance started. And now they are getting married - it’s like a fairytale unravelling in front of our eyes. The scene has got to get back in there.”

Katy - who started dating Russell in September, four months before they got engaged - recently admitted she was attracted to Russell as soon as they worked together on the film: “When he was filming Get Him to the Greek, I did a cameo with him. My scene called for me to make out with him. And on the way down the stairs after the scene, I was hopping like a bunny. I hop like a bunny when I’m happy - I get a bit childlike.”

Get Him To The Greek - which also sees cameos from Pink and Tom Felton - is out in theaters on June 4.
