Twilight star Robert Pattinson will not be appearing on the Twilight Cruise, according to co-star Ashley Greene.

Robert, 23, plays the role of dreamy vampire Edward Cullen in the hit film series and Ashley, 22, plays Edward’s adoptive sister Alice Cullen.

Ashley will be joined by co-star Kellan Lutz, who plays Emmett Cullen, as the star attraction on a week’s ‘Twilight Cruise’ from Seattle to Alaska.

The journey will allow fans to meet Ashley and Kellan and get autographs and photos with the pair among other Twilight activities.

However, Ashley denied Robert will be joining them, saying: “I think he’s entirely too busy. He’s working on, like, eight movies.”

She also admitted she is nervous about the upcoming trip. Ashley said: “I don’t know how it will turn out, because we’ll be on a boat, so that could be interesting.

“Luckily, my dad will be there, so he can be my bodyguard.”
