Let's make this birthday one to remember.

47 years old (Born on January 15, 1978)

Happy Birthday, Eddie Cahill! From charming us as Tag Jones on "Friends," where your youthful charisma made Rachel—and all of us—swoon, to keeping the streets safe as Detective Don Flack in "CSI: NY," you've always had a knack for stealing scenes (and hearts). Your ability to balance humor and intensity has truly stood the test of time.

Here's hoping your birthday is filled with fewer crime scenes and more cake slices. May this year bring you roles just as memorable—and hairstyles just as timeless—as those we've loved so far. Keep shining bright; you're our favorite detective-turned-assistant-turned-heartthrob!
