How about "The Bachelor and the Bobby-Soxer" (1947) about boy crazy high school girl who goes after a fun loving bachelor. The bachelor wants nothing to do with the teenager, but her aunt (who is a judge), well that's another story.
The Bachelor? A 43 year old Cary Grant.
The high school girl? A 19 year old Shirley Temple.
Yes, Shirley Temple was playing young (17 years old) in this movie, which was an attempt to transition Shirley Temple from child star to a regular star.
At one point she is threatened with a spanking. Someone on the internet captured the scene at:

Richard Nugent: Hey, you remind me of a man.
Susan Turner: What man?
Richard Nugent: Man with the power.
Susan Turner: What power?
Richard Nugent: Power of hoodoo.
Susan Turner: Hoodoo?
Richard Nugent: You do.
Susan Turner: Do what?
Richard Nugent: Remind me of a man.
Susan Turner: What man?
Richard Nugent: Man with the power.
