Manchester City star Jack Grealish is set to become an uncle this summer after his sister Kiera, 22, announced her pregnancy

Manchester City star Jack Grealish will become an uncle this summer after his younger sister announced she is pregnant.

Kiera Grealish, 22, will give birth to her first child with boyfriend Josh Murphy in August after announcing the news on social media.

It comes a week after they celebrated their four-year anniversary. The couple wrote on Instagram: “Baby Murphy… a dream come true, half mine and half yours.”

In addition to Kiera, Jack is also close to his other sister, Hollie, who was born with cerebral palsy.

Hollie said on the announcement post that she “can’t wait” to meet her niece or nephew later this year.

The father-to-be, Josh, is a model signed to Manchester modeling agency Nemesis.

In their Instagram post, the couple showed off photos of their first baby scan, a pregnancy test, baby booties and a photo of Josh kissing Kiera’s belly.

Jack’s long-time girlfriend, Sasha Attwood, also sent her well wishes, along with a number of other wives and friends of other footballers.

Things have been far from smooth on the pitch for Jack of late, after he suffered a groin injury during Manchester City’s midweek win over Copenhagen in the Champions League.

The 28-year-old limped off during the first half at Parken Stadium despite doing his best to stay on the pitch before eventually admitting he could not continue.

It was understood the England international was suffering from a muscle injury and a two to three week window was given for his recovery, as reported by The Telegraph.
