Alexandra Burke has revealed that her relatives were shocked by one of her revealing stage outfits, says a report.

The 21-year-old told a tabloid newspaper that her auntie and her father did not approve of the X Factor winner’s choice of sexy black leotard.

Alex wore the revealing outfit on the video to her latest single Start Without You.

She told The Sun: “The video has a brave look. It’s my choice. I wanted to come out of my box. I wore lace on Alan Carr’s chat show the other day. I get the body out.

“My auntie thought it was a bit much and my dad told me I can’t wear it out on the town.”

Alex revealed that she chose the track because she wanted a song to listen to in her new convertible automobile.

She said: “It’s kind of reggae meets pop. It was inspired by my Jamaican background and my new convertible.

“I really wanted to have a tune I could take down my roof to, drive along and be proud of. I didn’t really want to do a ballad. I love the summer and this is the perfect track to dance to.”

She added: “I call myself The Beast on stage and this song matches that perfectly because the first two lines are, ‘Ehh ehh, I’m like a beast.’ I heard it and really liked it.”
