Sarah Michelle Gellar has remembered her "little sister" Michelle Trachtenberg on what would've been her 40th birthday.

The actress passed away aged 39 in February from diabetes complications and Sarah took to Instagram on Saturday (11.10.25) to remember her Buffy the Vampire Slayer co-star on what would've been her milestone day.

The 48-year-old star - who first met Michelle on the set of soap opera All My Children in the early 1990s - captioned her post: "When you turned 16, it was hard not to still see you as the little girl I met on All My Children. When you turned 21, I had to teach myself to not see you as the little sister anymore."

Sarah added: "I can’t imagine what 40 would have been like. This I know … it would be filled with love. Happy birthday @michelletrachtenberg."
