Katie Holmes used social media to honor her mother Kathleen Stothers-Holmes's birthday in the sweetest way Wednesday.

Holmes began the celebration by sharing an old photo of her mom as a kid which she paired with a heartfelt message to the family matriarch.

"Happy Birthday to my beautiful kind smart determined loving courageous mom!!!!!!! We are so blessed to be your children and to have our children have u as their grandma," she wrote and included a red heart emoji and the hashtags #inspiration #joy #strength and #love.

Holmes's next post showed the actress and her mom smiling on a New York City rooftop. The duo attended the Cartier Fifth Avenue Mansion opening party together on Wednesday and a photo posted later in the day shows them holding hands with a caption identifying their Cartier and Valentino jewelry and the hashtag "#mymomandme."

Holmes, who is the youngest of her parents' five children, enjoys a close relationship with her mother, as does her own daughter, Suri.

Happy birthday, Kathleen!
