"Biggest debut yet," MGK captioned the Instagram, "it’s a celebrationnnnn."
Since their daughter's March 27 arrival, MGK and Megan—who called off their two-year engagement in December—have kept their baby mostly out of the public eye.
However, the rapper—who is also dad to 15-year-old daughter Casie with ex Emma Cannon—did offer another rare glimpse at his youngest kiddo earlier this month, when he shared a selfie of him holding her against his chest taken through the reflection of a car window.
“Stop what you’re doing,” MGK captioned the May 22 Instagram post, which also included photos of him with friends and getting his hair done. “These pictures are v important.”
Plus, the "Lonely Road" musician has provided an update on the newborn's health, revealing that she was home sick when he made a brief appearance at the 2025 American Music Awards on May 26.
"Baby's great," he exclusively told E! News at the award show. "She has a little bit of a fever, so I'm gonna just walk the carpet and go back, you know what I mean, and handle my business. Give her my pheromones, and let her heal up."

Breakfast In Bed
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.
Swimming In Smiles
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.

Girl Dad
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.
Special Occasions
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.”
Christmas Card
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.
The Look of Love
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."
Three's Company
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.
Musical Prodigy
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."
Mama Bear
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."
Bookworm
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."
Co-Parenting Pros
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."
Keeping the Peace
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.
Pool Day
Brian snapped a pic of his brood having some fun in the sun in Malibu, captioning the Instagram post, "Great day!!"
Kicking the Habit
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."
Stepmom Supreme
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.'"
Past Their Bedtime
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."
Helping Hand
No job is too big for the TV star and his mini-mes.
More to Come?
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."
The Family Grows Again
On March 27, 2025, Megan and MGK welcomed the newest member of their blended family: a baby girl, who arrived into the world with her own original score composed by the rocker and his musical pals including Travis Barker.
"She’s finally here," MGK exclaimed in a post on Instagram, "our little celestial seed."
They Scream for Ice Cream
Brian and Sharna enjoyed a sweet treat and some sweet laughs with Zion, Noah, Bodhi and Journey in April 2025.
Just Hanging
MGK spent quality time with his oldest daughter Casie shortly after announcing the birth of his and Megan's baby girl.
