Alexandra Burke loves her own songs

The 'Bad Boys' singer amazed revellers at London's Mahiki nightclub last night (20.05.10) when she took to the dancefloor with her sister – to show off her moves to her own hit, 'All Night Long'.

One onlooker said: "Alexandra was in really good spirits and seemed to be having a good time. She really threw herself into dancing to her own song – though she seemed a bit unsure of the words!"

Earlier in the evening, the 21-year-old star had expressed her intention to do some dancing as soon as she had the chance.

She told BANG Showbiz: "I really need to get my groove on! But I keep getting pulled in all different directions – it's mad!"

She also boasted she could "drink everyone under the table".

Alexandra also revealed she is hoping to land a sponsorship deal to get free tomato ketchup as she puts it on all of her food.

She said: "Honestly, I eat so much of the stuff they should have me representing them. I eat ketchup with everything – even roast dinners! I'd probably get a lifetime supply if I was a Heinz spokesperson."

The star left Mahiki at midnight.
