Collingwood's Jack Crisp and wife Mikayla welcome third child two weeks after AFL Grand Final: 'Our little princess'

AFL star Jack Crisp and wife Mikayla have welcomed their third child together.

The couple shared the happy news with fans on Instagram on Thursday, almost two weeks after Collingwood won the Grand Final, revealing they had a daughter named Murphy Jay Crisp.

Jack, 30, shared a series of pictures from the hospital room and of their tiny tot, writing that she is their ''third little princess".

Watch the video above.

"Murphy Jay Crisp. Completing our family with our third little princess #girldad #luckiestguyintheworld," he sweetly captioned his post.

In the pictures, the couple can be seen doting on their newborn and in one image, they placed his 2023 AFL premiership medal around the baby as she posed with her older siblings Lilah and Sloane.

Mikayla also shared a series of posts and said Jack was ''her rock'' during labour.

She also shared a sweet video of Jack doting on their tiny tot and kissing her, writing that he's "smitten".

Mikayla also shared a picture of herself showing off her post-partum baby belly and wrote: "Isn't the female body so incredible."

The WAG added: "Day one post-partum, let's go!"

Just two weeks ago, Jack helped Collingwood go to victory in the AFL Grand Final.

"Jack I am so proud of you, you did it!" Mikayla wrote in one post at the time. And Happy Birthday my love, hope it feels like the best one yet."

The pair tied the knot in 2016.
