Rocker Keith Richards puts his daughters' boyfriends to the test by intimidating them with bizarre knife tricks.
The Rolling Stones legend is "quite protective" of his girls Theodora, 26, and 25-year-old Alexandra, his children with Patti Hansen.
And Alexandra, who is dating DJ Nick Cohen, reveals her dad goes to extreme lengths to gauge whether their partners are suitable.
She tells Hola! Argentina magazine, "Sometimes he takes boyfriends to the other end of the house to show them some tricks with a knife. It's to intimidate them a little, to warn them they shouldn't make me or my sister suffer. But then he's very pleasant."
"I think he trusts my instincts and that I know what makes me happy."
