The Jonas Brothers' mother "prays" they stay virgins until they're married.
Denise Jonas - whose singing sons Nick, Joe and Kevin wear chastity rings - hopes her boys won't succumb to temptations of the flesh, but vows she "won't hate them" if they do.
She said: "They are men. They have desires. They have testosterone. If they make a mistake, I'm not going to hate them. I don't think they are above or below being seduced. I would be foolish if I thought that. I pray for them."
Nick, 17, says his mother taught him and his brothers everything from good manners and proper dining etiquette to how to behave in hotels when touring.
He explained to Good Housekeeping magazine: "She makes us be careful in the hotel room. She makes us put back the towels, straighten the bed."
Even though Denise runs a strict household, her sons adore her and Joe, 19, claims any prospective girlfriends must love her too.
He said: "People always ask, 'What's a girl have to do to get your attention?' I say, 'She has to be good to mom.' "
