So we asked Sofia Richie about rumors she's engaged to bad boy boyfriend Scott Disick and guess what she said ...

Nothing! Not surprising; the teen certainly isn't going to dish the good news to X17online first, though we wish she would. She's probably have to go to her dad Lionel first -- and Scott would be smart to ask the pop star for his daughter's hand in marriage, though we wonder if he'd grant it.

Lionel said a few weeks ago that he is "scared to death" of his 19-year-old daughter dating the notoriously bad Lord Disick. But Sofia recently claimed her dad has changed his tune and that he's now "cool" with the relationship, telling E! News: "He's good. He's been very nice. He's been very cool. He's very supportive, whatever that means."

Hmmm ... we think Lionel's probably praying every night before bed that Scott doesn't pull something and propose!
