The Sixteen Candles star spoke to Reddit in one of the website's signature Ask Me Anything interviews, where she opened up about the secret to staying young.
"I drink the blood of Kristen Stewart," Ringwald teased.
The actress also spoke about what she would take with her during a zombie apocalypse.
"They'd slow me down but I'd have to take my 2-year-old twins," Ringwald said. "My older daughter Mathilda is pretty fierce so I'd need her on my team.
"Luckily my husband is a third degree black belt in Tae Kwon Do. He can break boards with his butt. Just bragging."
Last year, Ringwald confessed that growing up was difficult since people saw her as a perennial teenager.
The actress has said that she will not allow her children to act until they are older.
