Could this pregnant star and her husband BE any cuter?!

If there's one star who seems to be taking pregnancy in her stride and enjoying every minute of it, it's Olympic swimmer Rebecca Adlington.

Taking to Instagram to prove just how much craic she and her other half Harry are having with this whole baby thing, the gorgeous athlete posted a shot of them comparing 'baby bumps'.

Sporting matching black work-out gear, the couple posed for a selfie in a gym mirror and proved that their competitive streak isn't reserved for the swimming pool.

Captioning the cute shot: "He's so competitive, he had to have the bigger bump!! #whoworeitbest #bumpoff @harryneeds", Rebecca gave us yet another reason to love her.

26-year-old Rebecca will be welcoming their much-anticipated arrival on the 4th of June and by the looks of Harry's Instagram, he can't wait that long.

Sharing yet another ridiculously cute photo on social media, good-humoured Harry posed with possibly the teeniest pair of swimming togs we've ever seen and left us in no doubt that he plans for his little one to take after its parents.

The professional swimmer captioned the snap: "Had to buy this costume with @beckyadlington in preparation for @beckyswimstars lessons #prouddad #notevenborn yet #willcry #notevengotanameyet #knobofadad"

Oh, we heart them!
