Lisa Rinna is throwing it way back in honor of her daughter Amelia’s 19th birthday.

In an Instagram post, the Real Housewives of Beverly Hills star decided to give her daughter a sweet birthday gift: a nude photograph taken when she was pregnant.

In the picture, Lisa smiles at the camera while cradling her bare baby bump (which is clearly Amelia)!

“June 13,” she wrote in the caption. How sweet is this?
