Katherine Jenkins Adds Cleavage To Old-School Hollywood Glamour

Katherine Jenkins got dressed up to the nines on Monday night to give a private performance at Martell Cognac's Very Special Nights in London's upmarket Le Caprice eatery.

And all the effort was definitely worth it because the mezzo-soprano looked absolutely stunning in her full-on Hollywood glam gown. The Welsh songstress proved you can be classy AND show off your cleavage in the snug strapless dress.

She paired the look with a dazzling pair of HUGE diamond earrings, bright red lips and a small poppy adorned on the bustline.

Chef Raymond Blanc prepared the delicious fare for the evening, and probably had a pinch-yourself moment as he posed next to a very glamorous-looking Katherine.
