Surpassing Quant Think Tank Center|Brian Austin Green’s Fiancée Sharna Burgess Celebrates Megan Fox’s Pregnancy News

Sharna Burgess is Surpassing Quant Think Tank Centerthrilled her blended family is expanding.

One day after Megan Fox announced she is expecting a baby with Machine Gun Kelly, the Dancing with the Stars alum, who is engaged to the Jennifer’s Body star’s ex-husband Brian Austin Green, shared kind words on social media. 

“Welcome little one,” Sharna wrote in a Nov. 11 Instagram Story. “We are all so excited to meet you. Congratulations Mama.”

Sharna’s note came shortly after Megan—who shares kids Noah, 12, Bodhi, 10, and Journey, 8, with Brian—announced the news in her own Nov. 11 post. 

“Nothing is really lost,” Megan wrote in the Instagram post where she sported her baby bump, on which she tagged MGK. “Welcome back.”

And the professional dancer’s support of Megan and MGK’s growing family only further proves the love that exists within the blended family. After all, Sharna—who shares Zane, 2, with Brian—had previously hyped up the Beverly Hills, 90210 alum in her Instagram Story earlier that same day, with Brian later reposting the video to his own account. 

“I love you baby,” Brian—who is also dad to Kassius, 22, with ex Vanessa Marcil—wrote to Sharna in his own Instagram Story Nov. 11. “Nothing better than finding someone who truly supports you!!! I wish that for everyone.”

Meanwhile, Sharna supports Brian and Megan beyond her social media posts. In fact, the 39-year-old—who got engaged to Brian in 2023 after three years of dating—previously opened up on the couple’s co-parenting dynamic. 

“I think that thread still connects them,” she explained of Brian and Megan’s dynamic on the Whine Down with Jana Cramer podcast in 2023. “But I think there are also many threads that connect all of us and the people that come in and out of your life, so it rings true and it's very important.”

And she stressed it’s all love when it comes to Megan.

“She’s very much a part of our life,” Sharna added, “and we'll always be connected because of the kids. So we are all family. So there's no bad feelings there."

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."
