Jack Osbourne and Gearhart wed at the San Ysidro Ranch in California last week
For the post, Osbourne uploaded Jack's wedding photo — featuring the recently wed duo under a canopy of trees — and expressed just how excited she is for the pair's next steps in life.
Several fans and friends of the Osbourne clan celebrated along with Sharon in her comment section, including Gearhart herself, who wrote to her mother-in-law: "love you ❤️."
As previously reported, the pair secretly wed at the San Ysidro Ranch in California earlier this month, as both Gearhart and Jack (the youngest of Sharon and Ozzy Osbourne's three children) shared the same wedding pic to their own Instagram accounts.
"Something really cool happened," Jack captioned the photo, which features him wearing a pink-tinted blazer as his bride dons a stunning white gown. "I married the most amazing women I’ve ever met. All in."
Gearhart wrote under her post: "snuck away and married my best friend last week. i am honored to be your wife. all in forever 🌿"

It's been nearly four years since the Jack and Gearhart stepped out for their first public outing as a couple at the American Music Awards in November 2019. Two years later, they got engaged.
During the proposal announcement on Instagram in 2021, Jack called his now-wife the "most beautiful and loving woman I've ever met," and wrote that he was "so excited to walk through this one with her."
"Today my best friend asked me to marry him in a magical winter wonderland," Gearhart added. “I'll love you forever and then some @jackosbourne. my soulmate, my adventure partner, my protector. i'm ready for forever w you + our tribe."
The couple welcomed their first child together, Maple Artemis Osbourne, in July 2022. Jack also has three elder daughters: Pearl Clementine, 11, Andy Rose, 8, and Minnie Theodora, 5, all of whom he shares with ex-wife Lisa Stelly.
When his youngest was born last year, the Fright Club star wrote that his now-wife and baby were "doing great and are happy and healthy."
And as the family grows, Sharon continues to embrace her grandkids. In an Instagram post shared earlier this month, the grandmother posed with the five little ones — Kelly Osbourne's son Sidney, and all four of Jack's kids — for a sweet family photo.
"My Cup Runneth Over ❤️," she captioned the shot.
