Tyler Blackburn is well-known for playing Caleb Rivers on Pretty Little Liars, but nowadays, he’s heating things up on Roswell, New Mexico. While his character Alex has certainly caused a fan frenzy, the 32-year-old actor is just as swoon-worthy off screen. When he’s not filming the CW series, Tyler is jetting off to tropical getaways and showing off his glorious abs.

Grab a glass of water as you scroll through his hottest snaps ahead.
