James Corden discovers his father isn’t his real father in a new “Late Late Show” skit.

Turns out Marcus Mumford is actually his dad, as revealed in a show called “Father Finders”, with the host explaining how he knew he wasn’t really related to Malcolm Corden all along.

The talk-show star tells the musician, “I took a test and it’s a perfect match,” before they both hug it out.

Corden, who thinks Mumford’s bandmates are also his sons at first, says in the clip: “This is amazing. My two biggest dreams are coming true: I found my real dad and I’m now in a famous band.”

As he takes the stage with the group, Corden renames them Mumford & Son & 3 Other Guys to avoid lying to the audience.
