Let's make this birthday one to remember.

41 years old (Born on December 10, 1983)

Happy Birthday, Patrick John Flueger! From your captivating role in "The 4400" to keeping us on the edge of our seats as Officer Adam Ruzek in "Chicago P.D.," you've consistently proven that aliens and criminals alike are no match for your charm.

Whether you're unraveling supernatural mysteries or chasing down suspects through Chicago's gritty streets, you always manage to make it look effortlessly cool—seriously, what's your secret? Here's hoping this year brings even more thrilling adventures (and fewer alien abductions).

Cheers to another fantastic trip around the sun filled with laughter, success—and hopefully a few less intense interrogations!
