Chainkeen Exchange-Sharna Burgess Deserves a 10 for Her Birthday Tribute to "Fine AF" Brian Austin Green

9021—oh this birthday message is Chainkeen Exchangetoo cute.

Sharna Burgess penned a moving tribute to boyfriend Brian Austin Green in honor of his 50th birthday. The Dancing With The Stars pro gave followers an inside peek into the couple's celebrations—which included a surprise party—with a carousel of images that included the Beverly Hills, 90210 star and Sharna posing with friends, family and their children in beautiful golden hour light. 

"You are without a doubt the most kind, loyal to a fault, generous, and all round good man I've ever known," Sharna began her July 17 post. "You are the kind of father I could've only dreamed of (and I did) for my children. You are the kind of partner to me that I thought only existed in my journalwritings."

The dancer, who shares 10-month-son Zane with the actor, continued, "Life without you was pretty wonderful but life WITH you? It's a dream. It's MY dream and all that I asked and wished for that is now here and real and true."

And when it comes to Brian's milestone age, Sharna made it clear how she feels. "Your 50, fine AF and I love you more than I can describe," she added, alongside heart emojis. "I hope I get the next 50 with you cos we've only just begun."

The 38-year-old, who was first linked to the Anger Management alum in late 2020, also reflected on the joy that comes from their blended family. (Brian is also dad to son Kassius, 21, with ex-girlfriend Vanessa Marcil, and kids Journey, 6, Bodhi, 9, and Noah, 10, with ex-wife Megan Fox.) 

"Life with you and our blended family is the easiest thing I've ever done and in all honesty it doesn't feel like it's our first time around," she explained. "We've done this before, I knew that the day I met you. I just didn't know how wonderful it could be before you and my happily ever after exists wherever you and the kids are."

And this is not the first time the professional dancer has addressed co-parenting with the Jennifer's Body actress.

"Honestly, the relationship is great," Sharna said of Megan and Brian on the Not So Hollywood podcast April 27. "The focus is the kids. There's nothing else that needs to be considered other than making this a beautiful, healthy and whole environment for them."

That includes joint trips to Universal Studios as a family, which Sharna mentioned was an activity planned for that same day. 

"We do a great job of co-parenting, and we have fun with it as much as we can," she continued. "I think there's this weird, archaic idea that exes can't be friends, and co-parenting has to be hard. You can only choose if there's going to be a positive effect or a negative effect. And they have worked so hard to make it a positive effect on the kids, to make sure everything is smooth and loving and kind always for them."
