Who is the male vocalist on Alexandra Stan's "Mr. Saxobeat"?

You know, the one that sings "oh yeah, mmm yeah, mmm yeah".

His voice in that part gets stuck in my head all day.
It's SO sexy; I NEED to know who sings it.

For those of you who don't know the song, it's this one:

From 0:57 to 1:13
and then again
from 2:00 to 2:16

His voice turns me on so badly...does anyone else feel the same way?
