From big stars like Harry Potter’s Daniel Radcliffe and FHM’s #1 sexy female of 2008 Megan Fox to relatively unknowns ones such as Gemma Arterton of new James Bond flick Quantum of Solace and Anton Elchin of Terminator 4, they range but one thing they all have in common is being young and hot in Hollywood.

AOL’s Moviefone.com offered its 2nd Annual list of top 25 stars under age 25, and among popular celebrities there is Oscar-nominated Keira Knightley, 23, as well as Michael Cera, 20, of Juno.

Moviefone editor-in-chief Scott Robson said:

There are several returning people, but what’s really exciting is there’s this whole new crop coming up. We look at what they’ve done in the past, but we’re mostly concerned with what they have coming over the course of the next year and where it positions them.”

What’s the difference between such stars as Daniel Radcliffe, Megan Fox and Keira Knightley? Until recently they were united by nothing, except cinema, but now all of them entered a general rating – 25 hottest Hollywood stars aged till 25 years.
