Liv Tyler has been promoting her new book - on manners.
The Lord Of The Rings actress appeared on US show The View with her grandmother, etiquette expert Dorothea Johnson, to promote the book, MailOnline reported.
Asked whether her eight-year-old son Milo had impeccable manners all the time, the 36-year-old admitted: "Oh goodness no!
"He's really naturally a thoughtful, kind person. But when my grandmother's on her way in we panic.
"I'm not very hard on him, especially in the evening when he's just come home from school and he's tired, I'd prefer us just to enjoy a nice meal together."
Liv's grandmother Dorothea is the co-author of their book Modern Manners: Tools To Take You To The Top.
MailOnline quoted Liv, the daugther of Aerosmith's Steven Tyler, as saying: "It's all about thoughtfulness and being a kind, considerate, generous person.
"You don't have to have perfect manners to do that. You don't have to have a college education to know how to be a kind, thoughtful person."
