New mum Michelle Bridges has swapped her gym clothes for a breastpump.

Just last week, Michelle Bridges and partner Steve “Commando” Willis confirmed they have welcomed their first child, Axel Bridges Willis.

“Welcoming into the world Axel Bridges Willis born 19/12/15 at 8.05am and as cute as a button! Mum and Bub are absolutely fantastic, dad is too! Tears and joy all round!” the statement said.

Bridges also shared the beautiful news on her Instagram account.

But what do you get a new mum who has given birth so close to Christmas? Only one thing of course. A breast pump.

Michelle shared a picture of her new gift on Instagram, which she's sure will get a "real workout."

It is the Biggest Loser stars' first child together, although Commando already has three children, Ella, 6, Jack, 3, and Brianna, 15, from two previous relationships. Earlier this year, Bridges told Who magazine the couple couldn't wait to meet their child.

“We’re really looking forward to it and it’s a new chapter for us, and we’re excited to have the opportunity to share it with our friends, family and Steve’s beautiful children,” Bridges said.

And as the happy couple settle into the new year with their new little one, we hope Michelle can inspire us to get off our butts and back to the gym. Maybe.
