Model Irina Shayk has debuted her romance with Bradley Cooper online for the first time with a sexy hot tub selfie.
The catwalk beauty began dating The Hangover star in April, 2015 but they have kept their romance low-key and away from the spotlight, only making their official debut as a couple at a Paris Fashion Week event in France in March.
The 30-year-old, who managed to keep her boyfriend from her social media accounts for around a year, has now shown him off on Instagram for the first time.
The steamy picture, which was posted without a caption, focuses on their torsos and shows Irina sitting on a topless man's lap as they soak in a hot tub. Their heads are not included in the picture, but it's clear the guy is Bradley, 41, as his muscular right arm and shoulder and a portion of his stubbly neck are featured in the snap.
However, Irina, who has her arm extended to take the selfie, is the centre of attention in a dark green swimsuit which has a deep cleavage-baring gap, exposing a lot of skin.
The couple, which was hit with split rumours at the start of 2016, has not commented publicly on its romance but Bradley and Irina have been spotted kissing in public a number of times. The actor reportedly moved into her New York City apartment in November.
In March, Bradley accompanied her on the red carpet for the L'Oreal Red Obsession Party in Paris, and sat proudly in the front row while she was modelling in the Givenchy catwalk show.
The Russian supermodel previously dated Portuguese soccer player Cristiano Ronaldo for five years until January, 2015, while Bradley romanced actress/model Suki Waterhouse until March, 2015.
