Singer and actress Holly Valance has shown off her impressive engagement ring for the first time. 

The 'Kiss Kiss' star, who recently appeared on Strictly Come Dancing, made an appearance at last night's (January 17) Radio Times party where she debuted the huge rock for the first time since announcing her engagement to businessman Nick Candy just before Christmas. 

Valance told her fans the fantastic news via Twitter, where she posted a photograph of the romantic proposal scene and explained that it was the "happiest day" of her life.
