Cristiano Ronaldo's supermodel girlfriend Irina Shayk has been crowned World Cup WAG with the best hair.

In a poll conducted by Hairtrade.com, the 28-year-old brunette beauty beat the likes of Coleen Rooney, Christine Bleakley and Shakira to top the poll of WAGs with the most desirable locks winning 21 percent of the votes.

A respondent said of the Russian beauty: ''I love Irina Shayk's look. Her flowing brunette hair always looks in great condition and full of volume and shine. I wish I could get my hair to look as flawless as hers.''

Outside of her WAG duties, the Victoria's Secret star - who has also modelled for Armani Exchange, Sports Illustrated and featured in Kanye West's music video 'Power' - is set to make her acting debut in the new movie 'Hercules' which is out later this year.

Surprisingly, 'Waka Waka' singer Shakira's voluminous blonde curls only made it to fourth place on the list.

The 37-year-old pop star - the girlfriend of Spanish defender Gerard Pique - came in with 13 percent of votes behind England star Wayne Rooney's wife Coleen (17 percent) in second spot and Frank Lampard's fiancée Christine Bleakley (15 percent) in third.

Former 'The Apprentice' contestant Leah Totton - who is in a relationship with England goalkeeper Fraser Forster - came in at eighth place, scoring five 5 percent of the vote for her sleek blonde style.
