Will Smith surprises Jada Pinkett Smith onstage to declare his love for her

Will Smith has surprised his wife with a public declaration of love onstage.

Jada Pinkett Smith had been promoting her upcoming memoir, Worthy, at the Enoch Pratt Free Library in Baltimore, where she's from.

She was joined at the event by her A-list family, who were all in town visiting her mother, 70.

Will Smith, their children Jaden and Willow, as well as Will's son from a previous marriage, Trey, were all in attendance.

Jada had concluded a talk on her upcoming book when Will took the stage and made a declaration to the assembled audience.

The actor went on to talk about his relationship with Jada, and making a bizarre declaration of love.

He said: “Our union is a sloppy public experiment. It is a sloppy public experiment in unconditional love.

“As I stand here before you today, I am happier than I’ve ever been in my entire life.

“I have achieved every single thing I have ever wanted in my entire life. There is not one thing left that I desire in this world—all of the awards, all of the money, the family—everything I’ve ever dreamed.”

Will went on to credit Jada for his career, saying his successes 'were largely built on the foundation of Jada's sacrifices.'

He added: “Can you show up and love somebody for the rest of your life, even when you don’t agree with them?

“Jada is the best friend I have ever had on this planet and I am going to show up for her and support her for the rest of my life.”

It came after Jada revealed that the pair had been separated since 2016, and are now working on their relationship together.

She told People Magazine: "We've been doing some really heavy-duty work together.

"We just got deep love for each other and we are going to figure out what that looks like for us."

Explaining why the pair had decided to keep the separation private, she said: "I think, just not being ready yet. Still trying to figure out, between the two of us, how to be in partnership.

"And in regards to, how do we present that to people,” she said. “And we hadn’t figured that out.”
