Yesterday marked Sarah Michelle Gellar's daughter's seventh birthday.

And to celebrate the special day, Sarah took to Instagram to share a really sweet message about her.

Sharing a picture of her holding Charlotte Grace as a baby, the actress wrote: "Sometimes when I need a miracle, I look into my daughters eyes, and realise I've already created one. #happybirthdayCharlotte #thisis7."

Sarah and her hubby Freddie Prinze Jr welcomed Charlotte in 2009 and three years later their son Rocky was born.
