Song from oops tv dont know what it is?

Watched oops tv and there was a part where you had to guess who the
celeb was and it was paris hilton. but there was a song playing.

The person who it sounded like was rick astley

and ill try to describe it the best i can i think these were the
lyrics but im not 100 percent sure.

"leave me now.... forever your heart.." it sounded like an 80's
ballad.

Thanks anyways
