River Viiperi’s Hottest Instagram Photos

If you thought Justin Bieber liked to show off his bare booty on Instagram, River Viiperi's got him beat.

Not only is the Spanish-Finnish model not shy to take it all off, but those smoldering looks will make your temperature rise: he's modeled for the likes of Calvin Klein, Armani Exchange, American Eagle and Versace for H&M —oh yeah, he also famously dated Paris Hilton. (He's with model Nicole Banner now, but we don't think she'll mind us checking out her man.)

We gathered the hottest, most unabashedly shirtless photos from the 25-year-old model's Instagram, which you can see up top.
