Kris Smith and his partner Sarah Boulazeris just welcomed their first child together, a beautiful baby girl called Mila.
And even though she only gave birth just six weeks ago, personal trainer Sarah is already looking incredible.
The fit and fabulous mama, who has her own exercise program for mums-to-be called BUMPFIT, showed off her incredibly toned bikini body in a series of beautiful photos on Instagram.
Sarah says she's just beginning her "postpartum training journey", after being given the all clear to train again by her doctor. But yes, she did workout consistently throughout her pregnancy too.
"It feels amazing to be back in the [gym],' she wrote on Instagram.
"BUMPFIT kept my body and bump strong, mobile and healthy during my pregnancy. Now it's time to rebuild and strengthen my pelvic floor, core and body's overall strength and movement."
But she advised any new mothers to consult a doctor before starting any exercise post-birth.
"Before commencing postnatal training I received a clearance from a medical professional. I strongly advise you to do this also," Sarah said.
Kris and Sarah are clearly smitten with their newest addition - and proud dad Kris has been sharing loads of adorable selfies with Mila Elle on Instagram.
And he's already becoming super protective of his little girl.
"One week old and I'm already planning my Bad Boys 2 scene for her first date," he joked, referencing the hilarious famous scene where Martin Lawrence and Will Smith interrogate a young man who wants to date Lawrence's teenage daughter.
Kris started dating Sarah in 2017 and revealed that they were all set for their new arrival last month.
"The nursery is done, everything is organised, I am as ready as I will ever be," he told The Daily Telegraph.
"But Sarah is over it, she is ready to meet the little one, so am I."
Kris is already a dad to son Ethan, nine, with ex Dannii Minogue whom he dated for four years.
Speaking about their split in the South African jungle on I'm A Celebrity...Get Me Out Of Here, the former rugby player said that it reached a point where it simply didn't work for anyone in the relationship.
"We didn't wanna get in silly bickering arguments in front of Ethan. So the hardest thing I've had to do was leave. [Ethan] was very young but I didn't ever wanna see him in an environment where it's a little bit bitter or argumentative," he told his campmates.
"All I ever wanted in life was to settle down with one woman and have kids with one woman. It absolutely ripped my heart out but it was for the best."
Kris and Sarah announced their exciting baby news back in July via Instagram with snaps featuring some adorable baby sneakers.
"We're having a baby," the 40-year-old shared in his caption.
"My amazing woman is giving us the greatest gift on earth, a growing family.
"I couldn't be more proud of you baby, and I know Ethan and Harley are so excited to be big brothers."
