Jesse McCartney Pens His 'Chernobyl Diaries' As This Week's Hump Day Hottie

Jesse McCartney not only make us swoon as a pop star, but as an actor as well. Zac Efron’s one-time “Summerland” co-star sure has grown up since his days on The WB. And this week he stars in the creepy thriller, "Chernobyl Diaries." While he will have us screaming out of fright in his latest film, we have to say we’re more used to screaming for him in concert. Either way, he’s pretty sweet eye candy and this week’s Hump Day Hottie.

Check out this dreamy photo of Jesse and keep reading for more details about him!

Vital stats: The 25-year-old grew up in Westchester, NY, and quickly got the singing and acting bug. He kicked off his career at the age of seven when he hit up local theater productions before moving on to much bigger things, including his music career. Not only is he a successful solo singer with tracks like “Beautiful Soul” and “Shake,” but he’s also been in a boy band, Dream Street, and penned Leona Lewis’ inescapable 2007 hit, “Bleeding Love,” along with Ryan Tedder.

Where you might have already seen him: Aside from his impressive singing career, Jesse’s also been quite successful as an actor. He starred on the teen drama, “Summerland,” as well as ABC Family’s comedy, “Greek.” He also did his time on the soap opera, “All My Children.” He’s also hit the big screen in flicks like “Alvin and the Chipmunks” voicing Theodore, as well as smaller films like “Beware the Gonzo.”

Why you should take notice of him now: This week he will face the unknown (read: scary) in the thriller the “Chernobyl Diaries” about a group of tourists who think visiting the site of a former nuclear power plant is a good idea. He’s also set to voice some more characters in animated features, “The Clockwork Girl” and “Tinker Bell: Secret of the Wings” alongside Lucy Hale and has been working on new music.

Until next week, when we choose another Hump Day Hottie, you can salute Jesse by staring at the photo above!
