Serena Williams knows just how to thank her Instagram followers — with an adorable picture of her daughter.

On Monday, the tennis icon, 37, celebrated reaching 10 million followers by sharing a look at her mother-daughter playtime in a sandbox.

In the snapshot, 13-month-old Alexis Olympia, her child with husband Alexis Ohanian, frolics in a one-piece with the words “More Issues Than Vogue.” Williams beams as she playfully reaches out for her daughter.

With two red hearts, Williams captioned the picture, “For my 10 million followers. Thank you.”
