Lady Gaga's wedding dress will shock you, but not in the way you think!

Los Angeles - 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 after four years of dating - are expected to tie the knot later this summer.
