The couple regularly share pictures and videos of their activities.
Like many partners during lockdown, Sims gave her boyfriend a DIY haircut.
And in the spirit of many lockdown haircuts, it did not turn out as planned.
“Bowl cuts are back,” was the message Koepka tweeted out to his fans.
In the accompanying video, the golf star is wearing a hat which is then ripped off by Sims to reveal the new trim.
With the PGA Tour now back in action after the coronavirus-enforced hiatus, Koepka is attempting to win PGA Championship for the third year running.
