(Cover) - EN Star Style - Beyonc Knowles felt like "a queen" in her latest promo because the costumes and jewellery were so good.

The singer has debuted the video for her track Best Thing I Never Had, and in it she gets married. Although she found the experience of walking down the aisle with a stand-in husband "creepy", the star who wed Jay-Z in a secret ceremony in 2008 did enjoy getting dressed up.

She was a particular fan of the tiara, made by Lorraine Schwartz, which she rocks in the promo.

"It was actually a necklace that she turned into that crazy crown," she giggled. "I felt like a queen."

Beyonc dons a Baracci dress in the promo, revealing it was something she'd hoped to wear for some time. It features embroidery, jewels and ruching and the 29-year-old star fell in love with it as soon as she saw it.

"It was an amazing Baracci dress that I saw in the window maybe a year ago when I was at the Grammys," she explained to Access Hollywood. "It was just like a beautiful fantasy, so we called and they still had the dress." (C) Cover Media
