Will Smith Mourns Prince's Death: ''I Just Spoke With Him Last Night''

"I am stunned and heartbroken," the actor added

One of the final conversations Prince had before his death was with Will Smith.

The legendary pop star died at age 57 Thursday at his Paisley Park studio in Minnesota. Authorities found him unresponsive in an elevator and were unable to revive him. His death remains under investigation.

"I am stunned and heartbroken," Will, 47, said on Facebook. "I just spoke with him last night. Today, Jada & I mourn with all of you the loss of a beautiful poet, a true inspiration, and one of the most magnificent artists to ever grace this earth."

The actor did not reveal what he and Prince talked about. Will, one of several celebs to post online tributes to Prince, also included a photo of the musician shredding on a guitar onstage at the Forum in Los Angeles in 1985, at the height of his career.

Will is also known for his own music career—he became a rapper in the '90s when he starred on the sitcom The Fresh Prince of Bel-Air. He is currently preparing a music comeback with a reunion tour with rap partner DJ Jazzy Jeff, set to take place this summer and start in the U.K.

Will's wife Jada Pinkett Smith, 44, also posted an online tribute to Prince.

"Prince was one of the first artists to put me on game in regard to the industry," she said on Facebook. "He was not only a genius artist, he was kind, funny, beautifully eccentric, curious, imaginative, magical, spiritual, rebellious and extremely intelligent."

"He showed me early the power of living one's life by one's own rules and no one else's," she added. "There are really no words to express what we have all lost today. To quote my friend Paress, 'Music has lost its heart beat.' Rest in peace Beauty...Jada."
