Alexandra Burke may have the No.1 single in the UK – which was the fastest selling single of the year – but she still loves shopping the high-street.

This weekend at the ‘Girlguiding UK’s Big Gig’ at Wembley Arena the singer was spotted wearing two Lipsy London one-sleeved dresses.

She walked the red carpet wearing a Lipsy London mesh one shoulder dress which she paired with knee-high suede boots.

She later performed wearing a Lipsy London VIP asymmetric animal sequin dress.

My favourite of the two is the blue dress. It kind of reminds me of the one-sleeved blue sequined Balmain Fall 2009 dress.
