Zac Efron thinks Robert Pattinson is "amazing".

The 'High School Musical' actor is a big admirer of the 'Twilight' hunk and is particularly impressed with the way the 23-year-old British star is handling his fame.

He said: "He's absolutely amazing. I think he's making great choices. I think he's handling it all really well, but you know, he's a superstar. He really deserves all this."

The 22-year-old actor arrived at the Academy Awards last night (07.03.10) without girlfriend Vanessa Hudgens, but says she wants his support when she picks up the ShoWest Star of Tomorrow Award in Las Vegas later this month.

However, Zac is unsure whether he can trust himself in the city, which is famed as a gambling and partying haven.

He told US TV show 'Access Hollywood': "She's trying to get me to go to Vegas. I've not been to Vegas legal yet, since turning 21. I feel like I might get into trouble."

Zac was among a number of young presenters at the 82nd Academy Awards, with 'Hannah Montana' star Miley Cyrus and 'Twilight' actor Taylor Lautner also working on the night.
