Orlando Bloom Appears to Check Out Kim Kardashian's Famous Backside

Orlando Bloom enjoys a nice view -- perhaps a little too much as he was caught seemingly staring at Kim Kardashian's famous booty.

The actor and his fiancée, Katy Perry, attended Monday's Kering Foundation's Caring for Women Dinner in NYC -- and were photographed standing near Kim K with Orlando just behind her.

All three were exquisitely dressed ... Orlando was in a black tuxedo, Katy was in a flashy aqua blue dress and Kim was in a form-fitting white latex gown, accentuating her shapely derriere.

That's when Orlando's eyes evidently trailed down to Kim's backside or he zeroed in on some pesky fly buzzing around her rear. We're thinking it was the former.

Meanwhile, Orlando and Katy also hit the red carpet, where the couple posed for pictures. The images captured Orlando with his hand right above Katy's butt, leaving no doubt where OB's mind was at Monday night.
