Irina Shayk tops the sideboob league as she goes braless in a plunging white dress

She's used to modelling underwear for a living, but it seems that when it comes to everyday life Irina Shayk prefers to go braless.
The 26-year-old model seemed to have forgotten to put a bra on when she accompanied her boyfriend, Christiano, Ronaldo, to a football event today (Thursday).
Wearing a smart white blazer, that just happened to be low cut, Irina showed off just the right amount of side boob as she sat with her sportsman boyfriend.

However, it was a near wardrobe malfunction for the Russian model, who almost flashed some nipple as she laughed with Christiano.
The brunette was too busy to notice how much flesh she was showing off as she gazed at the footballer and giggled.
She teamed the white jacket with a large pair of sparkly earrings and a matching ring, while her dark hair was pulled back into a chic bun.
The pretty star was seen listening intently as her partner talked her through the draw ceremony for the UEFA Champions League at Grimaldi Forum in Monte Carlo, Monaco.

The footballer had also dressed for the occasion wearing a dark smart suit and an expensive-looking silver watch.
Perhaps Irina was fed up of wearing underwear following her latest shoot for Chinese lingerie brand La Clover.
In the pictures she shows off her incredible physique in numerous pictures showing off the colourful designs.
In one picture she sprawls across some satin bed sheets while wearing a red lace two-piece while in another shot she flexes on a chair in a silver number.

She's no stranger to posing in just a bra and knickers, having started her career as the face of Intimissi five years ago.
It wasn't long before she was gracing the hallowed pages of Sports Illustrated, and walking the catwalk at the luxurious Victoria's Secret fashion shows.
However, fans who want to see even more of the sultry star will be disappointed to learn that she will never pose nude for Playboy as she is 'too classy'.
She has said: ‘I would never do Playboy. Yes, I am a lingerie model, but I have class. Playboy offered me so much money last year. I was like: “No. Way.”'
