For many divorced couples, it can be tough to keep things civil let alone remain friends.
But for Emma Watkins and Lachlan Gillespie, aka the Yellow and Purple Wiggles respectively, there is no bad blood. In fact, Emma shared a sweet tribute to her ex-husband via Instagram for his special day.
Posting to social media, the Yellow Wiggle shared a photo of Lachlan surrounded by birthday cards and holding a Spiderman themed balloon.
"Happy Birthday Lachy ☂️🔮☯️💜 @lachy_wiggle," she captioned the snap, and while her post was flooded with similar birthday messages to the Purple Wiggle, many praised Emma for her thoughtful gesture.

"@emma_wiggle You have a heart ❤️ of gold!" one fan commented.
"He's the best and so are you. I love you both so so so much," wrote another.
"You're so sweet Emma! Happy birthday Lachy!!" penned one more.
Emma and Lachlan tied the knot in a stunning countryside ceremony in April 2016 but revealed they had parted ways via a joint statement two years later.
But the two remain close and in an exclusive chat with Now To Love, Emma described her and Lachy as "the best of friends."
"It's not a normal situation where we break up and then don't see each other. We actually work together every single day so it's nice to work with your best friend. I think that's what we realised, that we were best friends all along."
"My life wouldn't be my life without him as part of it. I honestly am so grateful. We've had our ups and downs but we've come out of it on the back end really appreciating each other, like more than we did before. We've grown up, and now it's just a different time."

Lachy has since moved on with ballet dancer Dana Stephensen, a senior artist with the Australian Ballet who he reportedly met while on the set of The Wiggles.
The ballet dancer shared some sweet tributes to Lachlan via her own Instagram page, the first featuring her son Jasper, whom she shares with her ex-husband Melbourne photographer Michael Kai, cuddling with the birthday boy that she simply captioned: "We love you!"
The second snap showed Dana planting a sweet kiss on Lachlan's cheek that Lachlan himself reposted on his own Instagram stories.
According to the Daily Telegraph, it's believed Lachlan remains on good terms with Emma and members of The Wiggles have embraced his new relationship with Dana.
"All The Wiggles members, including Emma, are really happy for Lachy," a source close to the group told the publication.
"He and Emma remain good friends and both wish the best for one another."
