Megan recently shared some private details about their relationship during an interview with Glamour, including that they only drink each other’s blood for “ritual purposes,” explaining that “It’s just a few drops, but yes, we do consume each other’s blood on occasion for ritual purposes only, adding that “It is controlled where it’s like, ‘Let’s shed a few drops of blood and each drink it.’”

She also took a moment to talk about her kids with ex husband Brian Austin Green, revealing that she is “so proud” of her kids, but she avoids sharing photos of them on social media, because she “can’t control the way other people react to my children.”
