Godfrey Gao, Jamie Campbell Bower, Robert Sheehan, and Aidan Turner in VH1's '20 Hot Guys You Need to Know In 2013'

Check it out, we have 4 of VH1's 20 Hot Guys You Need to Know in 2013!

Jamie Campbell Bower

2013 Projects To Watch: The Mortal Instruments: City of Bones (Aug 26)

Why Is He Hot This Year?: If Gao is on the verge of breaking out because of a juicy bit part in a popular YA film adaptation, the film's lead should also brace himself for success.

Things To Know About Him: Campbell Bower isn't a stranger to the fantasy genre. He was a Volturi in The Twilight Saga and Grindelwald, aka Dumbledore's crush/lover/enemy in Harry Potter and the Deathly Hallows. Oh, and he used to date Ginny Weasley.

Godfrey Gao

2013 Projects To Watch: The Mortal Instruments: City of Bones (Aug 26)

Why Is He Hot This Year?: Gao is a smoking hot Taiwanese model and actor who is crossing over to Western films in a big way with one of the more juicy roles in a film filled with eye candy, The Mortal Instruments: City of Bones. Also, he has a vocal online fan community.
Things To Know About Him: He was born in Taiwan, but moved to Canada at the age of 9, but then moved back to Taiwan to model and act in a plethora of teen dramas.

Robert Sheehan

2013 Projects To Watch: The Mortal Instruments: City of Bones (Aug 26)

Why Is He Hot This Year?: Sheehan is the third up-and-comer who could break out on The Mortal Instruments series alone. However, unlike Gao and Campbell Bower, he hasn't forged his path playing pretty boys, but character acting his way through cheeky anti-heroes and historical characters.

Things To Know About Him: Sheehan started acting professionally in his late teens in his native Ireland, grew in popularity and acclaim and jumped to the UK market with film roles and an electrifying performance in Misfits. He's appeared in a number of US films in supporting roles, but is poised for a crossover to Hollywood. Oh, and he apparently likes wine. That's good.

Aidan Turner

2013 Projects To Watch: The Mortal Instruments: City of Bones (Aug 26) & The Hobbit: The Desolation of Smaug (Dec 13)

Why Is He Hot This Year?: Turner is probably the most visible dwarf in The Hobbit being that he's the youngest, (arguably) the hottest, and the one least covered in make-up and his character is one of the more "human" ones in the trilogy. On the flip side, he'll be the mature elder of the pack in The Mortal Instruments, so he's got two places to be seen in different ways by fantasy audiences.
Things To Know About Him: He recently cut his hair, which would be sad, but it still looks really, really, really good.

Here's what Cassie had to say about this news:

I remember Harald interviewing Aidan for the first time and being like, all your hair, where did it go? And Aidan being like… “it was a wig?”
