Pete Davidson Appears to Have Chipped Tooth in Video, But it's fake

Pete Davidson's a chip off the ol' block ... the question -- did Kanye West knock his block off?

The answer is no, but we'll explain why it's a fair question in a minute.

Yeah, Pete's tooth looks chipped, but it's not.  Our Pete sources tell TMZ ... he's shooting a movie that requires a chipped tooth, so it's fake.  We don't know which movie, but we know he does not have a chipped tooth.

Oh, the baby ... it's Malcolm, the newborn of Olivia Munn and John Mulaney, whom they now call "Uncle Pete." Pete's reaction ... "Babies are all head." You hear Olivia and John cracking up in the background.

As for the Kanye thing ... remember, he recently said in a song he would kick Pete's ass.
