Brian Austin Green is focusing on his present. 

Shortly after his ex-wife Megan Fox shared that she and fiancé Machine Gun Kelly are expecting their first baby together, the Beverly Hills, 90210 alum and his fiancée Sharna Burgess had their own sweet messages for each other.

The Dancing With the Stars pro posted a throwback video to her Instagram Stories Nov. 11 featuring Brian—with whom she shares son Zane, 2—in the music video for his single "You Send Me" from his 1996 album One Stop Carnival. She captioned the video, "That's my man," adding a double heart gif.

Brian re-shared the video to his own account, and took a moment to praise Sharna, 39, adding a red heart emoji and writing, "I love you baby!!

"Nothing better than finding someone that truly supports you!!" the 51-year-old continued. "I wish that for everyone."

The post came hours after Megan and MGK—who got engaged 2022—revealed her pregnancy by posting a photo of herself holding her baby bump to Instagram with the caption, "Nothing is ever really lost. Welcome back."

As for Megan's history for Brian, the ‘90s heartthrob has been candid about the issues that led to him filing for divorce in 2020 after nine years of marriage. He noted the breaking point came when Megan could no longer stand the way he chewed—and it was moments like that which he believes can make or break a couple.

"That to me is when you either have to make the choice to say, 'OK, we're going to go into therapy, and we're gonna try to find our connection and we're gonna try to find what's going on now, or these things are going to sink us,'" Brian explained on the MisSPELLING podcast in October. "They're going to be the death of us. Because they just build up and build up and get worse and worse."

Still, Brian has stressed that he and Megan have a very important rule when it comes to coparenting their kids Noah, 12, Bodhi, 10, and Journey, 8.

"The number one," he told E! News in April, "is always make sure that everything is centered around the experience of the kids." 

Brian—who also shares son Kassius, 22, with ex Vanessa Marcil—pointed out that a couple's separation can affect their children, so he and Megan made a conscious choice to focus solely on ways to coparent effectively.

"The person that you were with that you're now separated from, you guys are separated for a reason," he continued, "because you didn't get along. So, you can't expect to then get along after the fact in raising your kids. So, you have to decide, 'OK, it's not about us getting along anymore. It's about us co-parenting, which is a totally different situation.'"

Brian Austin Green enjoyed a lazy morning snuggled up with kids Noah, born in 2012, Bodhi, born in 2014, and Journey, born in 2016, who he shares with ex Megan Fox.

After Brian and Megan split in 2020, the Beverly Hills, 90210 alum found love with his Dancing with the Stars pro partner Sharna Burgess. The two welcomed son Zane in 2022, and announced their engagement the following year.

Meanwhile, Machine Gun Kelly—whose real name is Colson Baker—welcomed daughter Casie with ex Emma Cannon in 2009. He went on to get engaged to Megan in 2023.

Despite her commitment to co-parenting, Megan has said it's not always a walk in the park. “It’s hard to not feel obligated to be with them all the time or to constantly feel like I’m not doing a good enough job,” she admitted to Glamour UK in 2022, “but I’m also separated from their father. So, I can only have them half of the time. That just is what it is.”

Brian's blended family includes his son Kassius, 22, whom he shares with ex Vanessa Marcil. The actor posed with Sharna and all five of his kids for a festive family photo in December 2023.

For Megan, motherhood keeps her grounded. "When I step back, I know how connected I am and I’ve always been and how present I’ve always been,” she told Sports Illustrated Swimsuit in 2023. “I see the reflection of the type of mother that I am in their eyes and in their behavior."

In 2022, the Jennifer's Body star posted a rare photo alongside the "Emo Girl" singer and his daughter, taken at his 27 Club Coffee shop in Ohio.

The hitmaker turns to his daughter for advice on his music. "I trust her opinion more than I trust my own now," he said on The Kelly Clarkson Show in 2021. "Like, she has her finger on the pulse of what's hot, or if I'm doing a song and it's the right one, she'll confirm it."

In honor of Mother's Day 2024, Brian paid a loving tribute to Sharna. "You are an incredible mother and fiancée," he wrote on Instagram, "and we all love you to death."

Megan rarely features Journey and his siblings on social media—for one very good reason. "I knew when they were very young, I wanted to try to protect them however I could, especially limiting their exposure to the internet," she told Glamour UK in 2022. "So far, we’ve done a really good job and we maintain their innocence in a lot of ways, but I know I can’t protect them forever."

Brian's golden rule for co-parenting? Picking his battles. "People make a mistake of thinking that they're gonna do things so the separation doesn't affect the kids," he told E! News in 2024. "Of course it's gonna affect the kids. The only choice you have is how it affects the kids."

Likewise, Megan makes a point not to speak ill of her kids' father around them. "I don't let anything in my energy like that when I'm around my kids," she said on The Drew Barrymore Show in 2023, "because if I don't accept and love their father, I'm rejecting a part of them, because he's a part of who they are always.

Brian snapped a pic of his brood having some fun in the sun in Malibu, captioning the Instagram post, "Great day!!"

MGK—pictured with Casie at the Kids' Choice Awards in 2019—credited his daughter with helping him get clean after she told him she knew when he was high. "That was step one for me," the musician, who has been sober since August 2023, said on the Million Dollaz Worth of Game podcast. "As a father and as a man, to be the father I wish my dad would have been, I have to break this generational curse for my kid."

Sharna has thanked Brian's kids for preparing her to be a mom. "I got to test out motherhood with these guys," she said on the Quite Frankly podcast in 2023. "I got to learn things and grow with them, about parenting and understanding kids ... and knowing, 'Oh my God, I think I can be really good at that.'"

In 2020, Brian was a celebrity contestant on The Masked Singer. "I was super excited for my kids to watch it with me," he wrote on Instagram, but "they fell asleep after 15 min."

No job is too big for the TV star and his mini-mes.

While Brian revealed he got a vasectomy eight weeks after Zane was born, that doesn't mean he couldn't have it reversed down the road. "If we have the space and the ability to, would we love to? I certainly would," Sharna said on the Oldish podcast in January. "But we do have four young kids in the home and life is very, very busy."
