Robert Pattinson has joked he's been ''moisturising'' continuously in case he's called upon to reprise his role in the 'Twilight Saga'.

The 32-year-old actor achieved global fame through his starring role in the hit vampire-themed fantasy movies - which also featured his ex-girlfriend Kristen Stewart and Taylor Lautner - and Pattinosn has joked that he's ready to become vampire Edward Cullen if required and keeps his skin looking as young as possible in preparation.

He quipped: ''I was literally just talking to my agent about it. The amount of time I've spent moisturising, I am ready to play 17 at a moment's notice. Ready! I've got the Botox out! I can do it.''

In the film series, Robert plays the part of a 100-year-old vampire who is stuck in the body of a 17-year-old adolescent.

The first of the 'Twilight' movies was released in November 2008, and Pattinson can scarcely believe the film is already approaching its tenth anniversary.

He told Variety: ''It definitely doesn't feel like 10 years ago.

''I feel like I stopped mentally progressing around the time when I started doing those movies, so it feels like not a day has passed.''

Kristen - who dated Robert until 2012 - previously admitted to feeling similarly about the money-spinning film franchise.

Speaking earlier this year, the 28-year-old Hollywood star - who played Bella Swan in the 'Twilight' movies - said: ''It has been a long time. I don't know, it is funny. I have also lived in the same neighbourhood for 10 years and I thought about that the other day, and I was like, 'Oh god, you know, a decade ago it wasn't as crowded, and I was like, that is bizarre to be able to say that.'

''Certain things, certain memories will be close to you forever.''
