Purple Wiggle Lachy Gillespie and his fiancée Dana Stephenson are in celebration mode with the showbiz couple ringing in their twin daughters' milestone first birthday this week.
Ballet dancer Dana took to Instagram on Thursday evening to lead the tributes to her baby girls, Lulu and Lottie.
Sharing a precious snap of her two girls playing in a sea of balloons amongst a pile of unopened presents she wrote: "1 + 1 💕."
Meanwhile Purple Wiggle Lachy took to his Instagram Stories to reveal the number 1 cake he was going to make his daughters.
The Wiggles' power couple, who announced their engagement in April 2020, surprised fans by keeping their twin pregnancy under wraps.
Instead, they revealed the girls' safe arrival in September last year.
"Oh Lulu and Lottie, your mummy and daddy love you with all we have - you are both so beautiful - and I would love to sing to you both forever......... 🌈💜💜🌈," Lachy wrote at the time alongside a precious family snap.
Lachy is also the proud stepfather to Dana's son Jasper and it's a role his fiancée says he's taken to like a pro.
"You mean the world to so many people, your kindness, your generosity, your joy, your love shines through everything you do. But to these three little people, you are our whole world," the mother-of-three penned in tribute to the beloved children's entertainer on Father's Day earlier in the week.
"Our home, our hearts are so full of love and laughter everyday because of you. Each one of our beautiful children light up because of you, the greatest love a child could feel. We are so lucky and we adore you to every galaxy and beyond 💜 Happy Father's Day 💜."
The pair's romance was first confirmed in August 2019, after they fell for one another on the set of a Wiggles DVD special.
Lachy was previously married to bandmate and Yellow Wiggle Emma Watkins. The stars wed in 2016 before announcing their shock split just two years later.
