Lisa Marie Presley is a ''scary'' mother.

The 46-year-old singer is very protective of her kids, Riley, 24, and 21-year-old Benjamin - who she had with first husband Danny Keough - and five-year-old twins Harper and Finley, who she has with spouse Michael Lockwood.

Speaking on 'Oprah: Where Are They Now?' she said: ''I'm very, very much a very strong and intense lioness mother. Very scary, intense lioness mother.''

Lisa Marie admits she is so protective, her older children used to keep things from her.

She added: ''If something happened to them or someone was bullying or doing something, they knew that I would be very proactive in dealing with it, so they wouldn't tell me a lot. So I'm very, very protective number one. Also, [I] want to be their friend and protect them, but also get them to learn how to live in the world that we're living in.''

Lisa Marie also spoke of how she has taught her kids they will be ''loved'' because of their famous grandfather, late singing legend Elvis Presley.

She added: ''They kind of know, because they heard music and stuff and they've gotten the idea. I just say he was a very special person who sang and he touched a lot of people in the world and, and people loved him and they're going to love you because of him. And they kind of understand that.''
