#Twinning: Demi Moore and daughter Rumer Willis look identical in Instagram pic

Demi Moore and Rumer Willis are mother and daughter, but they could pass for sisters in a new photo.

Each wears a navy jumpsuit, dark-rimmed glasses and long, flowing locks in the image, which Willis shared on Instagram Sunday night.

"That moment when you realize you actually are becoming your mother #twinning #imnotmad," the 26-year-old captioned the shot of herself and her 52-year-old mom.

For her part, Moore shared the same picture on Twitter, writing, "Bookends!! #twinning."

Moore and Willis aren't the only famous mother-daughter duo who are nearly identical these days.
