Will Smith and Jada Pinkett Smith have been open about sharing details of their private lives with fans.

While you may be familiar with the headlines about Will's Oscars incident and the couple's separation, there's one surprising detail you might not know – Will Smith isn't actually called Will Smith.

Jada Pinkett Smith, in a previous birthday post, revealed his true name. In October, amidst revelations about their secret separation, Jada shared a throwback family photo in matching white outfits, featuring Will, Jaden, Willow, and Trey, the son from Will's previous marriage to Sheree Zampino.

Jada wrote in the caption: “I am so glad you were born on this day. Without you I would not have experienced the greatest joy of my life… the love of our family.

“On this Divine assignment we’ve chosen to walk together, I am grateful for the wells of laughter along the trails of tears we’ve shared.

“Thank you for helping me learn to embrace it all … with a smile. Here’s to 100+ more birthdays full of growth, acceptance and joy.”

In the opening of that caption, she addressed him by his full name – drumroll – Willard.

Yep, probably not what many fans of the King Richard actor were expecting as they commented on X: “I just found out today that Will Smith’s full name is Willard not William.”

Baffled by the revelation, they said: “Will Smith’s first name is Willard?!?!?!?!? Wtf…”

Pointing out what most of us were thinking, another quipped: “Why did I think Will Smith's full name is William and not Willard?”

“I was today years old when I learned that Will Smith’s name isn’t short for William but Willard,” one wrote.

And plenty echoed: “Will Smith real name is Willard, lmao I didn’t know that,” and: “Bruh never knew Will Smith’s real name was Willard. That’s so funny.”

Taking after his father, the actor known as the Fresh Prince of Bel-Air bears the full name Willard Carroll Smith II – certainly sounds more sophisticated than just Will Smith, to be fair.
