Lady GaGa's wedding dress is ''very simple and elegant''.

The 'Poker Face' hitmaker - whose real name is Stefani Germanotta - is known for her outlandish sense of style and unusual outfits but when she marries actor Taylor Kinney, she is going for a low-key look to prove she is taking her big day ''seriously''.

A source said: ''She's taking this step seriously and will marry Taylor as Stefani, not Gaga.

''Stefani is much more low-key than Gaga. She's commissioned her Haus of Gaga team to design the dress, but it's very simple and elegant.''

And the couple are planning a very ''traditional'' wedding celebration, with the reception taking place at the bride's father's New York restaurant Joanne Trattoria.

The source told heat magazine: ''After much thought, it's been decided there won't be any bovine dresses or fire-breathing priests.

''It's going to be a big traditional Italian wedding and she wants the reception to be held at her dad's restaurant.''

The couple - who got engaged on Valentine's Day (14.02.15) after four years of dating - are expected to tie the knot later this summer.
