It's safe to say Princess Charlotte has been dominating headlines since Kate Middleton gave birth [1] in early May, but she wasn't the first Charlotte with famous parents. On Wednesday, Sarah Michelle Gellar took to Instagram to share a hilarious picture of her daughter's perfect outfit for school — a pink t-shirt that reads, "I was Charlotte first." The actress even nailed it with the hashtags she used in her caption: "#PrincessCharlotte #PrincessCharlottePrinze."

Sarah and her husband, Freddie Prinze Jr., have been married for more than a decade, sharing more than a few supersweet moments together [3] over the years. They welcomed their daughter, Charlotte, who's now 5 years old, back in September 2009, and three years later, the couple's son, Rocky, was born. Check out more long-term celebrity couples [4], and see the sweet Father's Day snap SMG shared below.
