The couple are seen posing up a storm on a boat as they went scuba diving in the blue water and kicked back in the sea for the loved-up snaps.

However, in two pictures, Zach was spotted puffing on a cigarette, which left his fans concerned, especially since Ava, 24, is pregnant with their first child.

One person commented: “Smoking around her is crazy.”

Another Instagram user expressed: “Ok Zacahriah. How are you so into fitness and smoking. Noo not when your about to go into fatherhood. Just NO.”

Somebody else warned: “Second hand smoke is a thing, be careful.”

Yet another said: “I can’t believe people smoke in this day and age! It’s not like the old days when people didn’t know how harmful it is. You’re going to be a dad c’mon set a good example.”’

While a fifth concerned fan added: “Please don’t smoke around your pregnant girlfriend and especially the newborn.

“Second hand smoke can increase the risk of SIDS massively. Perfect time to try quitting.”

The pair announced they’re in February as he shared a scan picture on Instagram and penned: “Incoming summer ‘26.”

The two had previously dropped many telltale hints that suggested they had a baby on the way.

On December 18, Zach took to his Instagram stories revealing to fans that he had just received the “greatest news.”

He wrote: “Just found out the greatest news I think I’ve ever received. God must be real. Time to grind like never before.”

That same day Ava, who is daughter of star Caroline Hirons, took to her own page to repost an Instagram reel about pregnancy fitness training.

She then went on to upload one of her staple videos of her dancing where a baby bump could be seen peeking out underneath her hoodie.

In the following days, the pair also both followed a host of parenting accounts.

Earlier this week, Zach and Ava with a carousel of recent pictures to tell fans the happy news.

The first photo saw a stripey baby grow, hat, tiny shoes and 3D ultrasound pictures laid out on a bed.

In another snap, the couple cuddled up and beamed in delight.

They were both wearing black but Ava had her hair tied back in a blue scarf…

And, you might have guessed it, Ava and Zach captioned the post: “It’s a boy.”

Elsewhere, the former basketball player was spotted kissing Ava’s growing bump.

Their relationship was after the pair were caught by a TikTok influencer while having a stroll in London.

They solidified their relationship further by last month, in anticipation for the birth of their child.
