The supermodel, 37, wore a yellow and white bodysuit with a sheer knitted skirt on top, adding thigh high boots.

The runway star showcased her slim waist and her long legs in the striking sporty look – while posing with two tennis balls.

Her tennis themed shoot for Instagram comes just one day after it was revealed the statuesque beauty enjoyed a 48 hour rendezvous with Tom Brady in London over the weekend.

The former NFL player, 46, and Irina’s budding romance was revealed last month after they had a sleepover at his home

Tom and Irina spent Sunday and Monday together ‘holed up’ in The Twenty Two hotel in London’s Mayfair area – which is a five star hotel.

Prior to his drive to the hotel on Saturday night, Tom watched Birmingham City FC beat Leeds United 1-0; he is the new Chairman of the new Advisory Board for Birmingham City FC.

Tom arrived to the hotel early Sunday morning, checking in at 2 am after driving to London from Birmingham on Saturday night.

He left the hotel via a side entrance on Tuesday morning at 7:20 am as he headed to the airport to catch a flight out of London.

Irina left five minutes earlier on Tuesday morning via a side entrance.

The football hunk wore a hoodie, jeans and sneakers while carrying a camouflage duffle as he left the hotel on Tuesday morning.

Irina was seen leaving the hotel via the front at 9:45 am on Monday – returning at around 11:15 am.

The Russian supermodel wore a tiny pair of black and white leather-style shorts, adding a baggy striped collared top, a calf-length jacket and wedge boots.

Their 48-hour weekend rendezvous in London comes one month after their relationship was first brought to light.

In late July, photographers caught Tom and Irina cozying up in his car after they spent the night together.

According to an onlooker, Tom picked Irina up at a hotel on a Friday afternoon in late July and took her directly to his house.

They emerged from his property the following morning around 9.30am and he later dropped Shayk – who was wearing the same clothes from the night before – back at her hotel in his luxury car.

The legendary NFL quarterback – who is a seven-time Super Bowl champ – was caught gently caressing the Russian bombshell’s face following the overnight rendezvous at his Los Angeles home on Saturday night.

As he stroked her cheek, she looked at him longingly from the passenger’s side of his Rolls Royce.

On Saturday afternoon, Brady is understood to have collected her again from her hotel and returned to his house once more.

Meanwhile, a source close to the model confirms to DailyMail.com that the pair are ‘dating’ – although it is understood to be ‘early days’ between the pair.

Days after news broke of their budding relationship, the new couple enjoyed a date night in New York City, according to a Page Six eyewitness.

The lovebirds went to Sushi Azabu in Tribeca on July 28.

The football star was seen being escorted to a ‘private room’ at the eatery by employees minutes before Irina was seen coming in and being take to the same room.

‘It was just the two of them. They were just in their own little world. They clearly didn’t want to be around people,’ their insider said.

Irina has a daughter named Lea de Seine, six, with ex partner Bradley Cooper, 48; the runway star and the actor dated from 2015 until 2019.

Tom has two children with ex-wife supermodel Gisele Bundchen, 43: Vivian, 10, and Benjamin, 13; he also has a son named Jack, 15, from his previous relationship with model/actress Bridget Moynahan (they dated 2004 until 2006).

Gisele and Tom began dating in December 2006 and tied the knot in February 2009 they confirmed they were divorcing in October 2022 – after 13 years of marriage.

They revealed in the announcement that they had already finalized their divorce.
