Keanu Reeves' secret it out - the famous actor asked for two autographs, and things did not go as planned.

The most relatable guy in show business, Keanu, revealed to Stephen Colbert two celebrities he asked for their autographs.

The first one was from the late Lou Reed of Velvet Underground. Keanu explained:

"But it wasn't for me — it was for a friend, and [Lou] was cool about it."

"It was [on] a little piece of paper, and it was [in] blue ink. … Yeah, it was good. It just said, 'Lou Reed.' "

Considering Keanu was in a rock band, we are almost sure the autograph was not for a friend, but it is okay. Colbert joked:

"It would have been really disappointing if it didn't say Lou Reed."

Keanu still was not too happy about something as simple as writing your name:

"I know, but it could have said, 'All my best' or ..."

Now the second celebrity was far more quirky. Keanu asked legendary comedian George Carlin, with whom he appeared in 1989's Bill & Ted's Excellent Adventure, for his signature.

The comedian wrote:

"He wrote... I think it was 'Dear Keanu, F--- you'."

The Matrix star thought he was special, but...:

"I always thought he just wrote that for me. And then I met someone else who said that he wrote the same thing to them! Anyway, beautiful."

The star of Bill & Ted Face the Music remembers Carlin as "soft-spoken" and "not one of those guys who wants to take over a room."
