With one breakout role, Matthew Gray Gubler cemented his status in the pantheon of TV. hunks.
Criminal Minds fans fell in love with the actor — who celebrates his 46th birthday on March 9, 2026 — for his charismatic portrayal of Dr. Spencer Reid, a prodigious behavioral analyst. (It also helped that he had the best hair on the show!) Off-screen, Gubler continues to charm with his quirky social media presence, full of colorful paintings and an even more colorful personality.
Next, he's set to reassume the role of a genius in Einstein, a procedural series about a descendant of Albert Einstein. As he turns 46, look back at Gubler's most silly and swoon-worthy photos, from his first movie premiere to his best Instagram posts.

Not many people can say their first role was in a Wes Anderson film. In The Life Aquatic with Steve Zissou, he played an intern, cast by the director after Gubler had interned for him in real life. At the 2004 premiere, he sported his trademark long hair and an extremely chiseled jawline.
