Ogling Alert: Ashton Kutcher Checks Out Rumer Willis

It's hard to say where checking out the body of one's own teenage stepdaughter ranks on The Hollywood Gossip's ogling scale.

Certainly above the jaw-dropping, head-snapping, whistling, cat-calling antics exhibited by working-class British stiffs upon seeing Kate Middleton or Sienna Miller.

And probably even a bit higher than Diddy leering at Jessica Biel during an awards show. That body is something to behold, but the man's got Kim Porter and twins at home!

Yes, we'd have to say that Ashton Kutcher has raised (or lowered) the proverbial ogling bar by openly gawking at his wife's daughter, Rumer Willis…

Rumer's dad, Bruce Willis (also pictured here) has actually spoken quite fondly of Ashton Kutcher, the new, much younger husband of Demi Moore.

But the Die Hard actor has also been known to make thinly-veiled threats to anyone even thinking about trying something with his daughters.

Let's hope Bruce Willis doesn't get a look at this picture… and let's also hope Ashton doesn't decide to stare at Tallulah Willis next. That'd just be weird.
