She recently celebrated her boyfriend’s birthday wearing a plunging black dress.

And Little Mix singer Leigh-Anne Pinnock continued to show off her curves in a cute polka dot bikini while on holiday in Marbella on Sunday.

The 21-year-old singer soaked up the Spanish sunshine with her footballer boyfriend, Jordan Kiffin, 24, at the Ocean Beach Club Champagne spray party in Puerto Banus, Spain.

She revealed her stunning figure in a pretty black-and-white bikini, which featured polka dots and ruffles at the hips.

The star showed off her natural beauty by wearing no make-up apart from a slick of pink lipgloss and some hot pink nail polish.

She completed her look with a gold pendant necklace and a pair of cat eye sunglasses.

Leigh-Anne wore her curly hair loose and appeared to have recently dyed the tips of her hair a sun-kissed caramel shade.

She looked as if she didn’t have a care in the world as she sunned herself with one arm draped around her handsome boyfriend.

The singer was also spotted cracking open some bottles of champagne with a friend, and sipped the drinks while dipping her feet in the pool.

She has good reason to be cheerful as Little Mix will soon be rivalling fellow X-Factor band One Direction with their bank balances.

According to the Sun, the girl group have made £1.2million since winning The X Factor.

A source told the paper: ‘For a long time they were only on a very small amount of money, because it always takes a while for song royalties to come through. But now it’s started to come in thick and fast.’
