The actor is seen posing next to former South African president Mandela in the snap, which is being sold online for $25,000, and it’s thought it was taken around the time he was filming 2006 movie Blood Diamond.

It appeared on the website of autographs dealer Moments in Time this week, but Leo claims he has never seen it, the New York Post reports.

An inscription on the top right corner reads: “To Leo DiCaprio, Best Wishes, Mandela, 4-8-07.”

The website claims it owns the image rights, but keeps its source close, according to the New York Post.

But Leonardo wants the photo back, and his lawyers are reportedly considering taking legal action.

“The photo is clearly not their property,” a source told the news site.

“He wants the picture. His lawyers are considering action.”

We have contacted Leonardo’s reps for comment.
