Dermot O’Leary, 37, is on our screens every weekend at the moment presenting the X Factor, and on these cold winter nights he’s a ray of sunshine. The TV and radio presenter first made an impact on the UK presenting Big Brother spin-off show Big Brother’s Little Brother. With his snappy suits and his cool little trademark twirl ladies go weak at the knees for Mr O’Leary. Sad news though ladies, he already has a girlfriend.
