To celebrate her daughter turning 15 on Sunday, Holmes, who is famously private about the teen, posted three Instagram photos of Suri taken throughout the years. Homes shares the teen with ex-husband Tom Cruise, to whom she was married from 2006 to 2012.
In one of the pictures, Holmes cradles her look-alike daughter in arms. In another, Suri smiles for the camera while giving mom a big hug.
"Happy 15th Birthday Sweetheart! I love you!!!!!!!!" Holmes wrote in the caption. "I can’t believe you are already 15!"
Other stars gushed over the cute photos in the comments.
"Happy birthday," commented Viola Davis, adding a heart emoji.
"Happy happy 15th!!" wrote "Good Witch" star Bailee Madison. "Can’t believe she is 15 now. All my love to you both"
Though Holmes is known for keeping her daughter out of the spotlight, the "Dawson's Creek" star, 42, opened up about bonding with Suri during the coronavirus pandemic in her November cover story for Vogue Australia.
"Hobbies such as sewing, painting and writing became new hallmarks of satisfaction and having had time at home to just be," she wrote. "To listen. To live for a moment in time without the pressure of results and instead appreciate the natural rhythms of mother and daughter was the most precious gift."
Holmes also recalled how spending time with a friend with a young child made her reminisce about raising Suri.
"Taking time in Washington Square Park with a friend whose little child was taking his first steps brought me back to when my own child began to walk," she wrote. "I felt nostalgic and in awe of the power of time and the continuation of life."
