Zac Efron, 29, has always been a hottie, but recently he has matured from teenage dream to full-on hunk! We can't wait to see him flash his insane new abs in the upcoming "Baywatch" movie!
Alfred Enoch shot to fame as Dean Thomas in the iconic Harry Potter franchise, but who knew he would grow up to look this good? You can now catch the 28-year-old actor as Wes Gibbons on the soapy ABC drama "How To Get Away With Murder."
Michael Angarano, 29, from "Sky High" has grown up and is now a hottie! He has certainly come a long way from his days as Jack's son on "Will & Grace"!
Remember the little boy from "About a Boy"? Well, he's not so little anymore! Now 27, Nicholas has built himself a successful career in Hollywood as an adult. And we're happy to report that Jennifer Lawrence's off-and-on love is currently back on the market!
It's now our pleasure to reintroduce you to Matthew Lewis. You may remember him as Neville Longbottom from the "Harry Potter" franchise. The now-27-year-old British import now looks like a completely different person — a very hunky one!
Holy hotness! Where has Chris Pratt been hiding? The "Parks and Recreation" star, who reportedly lost 60 pounds to play Star-Lord in "Guardians of the Galaxy," is now one of Hollywood's hottest heartthrobs. Anna Faris is one lucky lady!

True Ryan Gosling fans may remember him as a Mouseketeer, as young Hercules or even as Alan in "Remember the Titans." But it wasn't until the aughts that the "Notebook" star became a heartthrob. Since then he's been charming audiences as Sebastian in the wildly successful flick "La La Land."
Can you believe Josh Peck is 30? But that's not the only reason why we did a double take when he hit the red carpet at the 2014 Kids' Choice Awards. The former child star has slimmed down — and grown up! — dramatically since his "Drake & Josh" days.
How hot is Joseph Gordon-Levitt? So hot that he even looked good in a dorky Christmas sweater. It's hard to believe this Hollywood hottie was once the kid with long hair on "3rd Rock From the Sun" and the nerd who couldn't get the girl in "10 Things I Hate About You."
If you're into the type of guy who rocks a neck beard, there's none finer than Hollywood bad boy Shia LaBeouf. Can you believe the sexy star, who stepped out in Los Angeles on the Fourth of July, was once the bratty younger brother in "Even Stevens"?
Prince Harry hasn't always been so charming. In fact, it wasn't until he launched his military career around 2005 that the fourth in line to the British throne really came into his own. But sorry would-be princesses, he's recently opted to settle down with a Hollywood star, "Suits" actress Meghan Markle.
