Everyone in Hollywood is related and it's blowing our minds.

As Oscars season approaches and Hollywood celebrities dominate our radar, we thought there was no better time than to blow a few minds and remind you that the movie business really is a small place.

And that there are far more celebrities who are related than we had ever really considered.

Melissa McCarthy and Mark Wahlberg

This is a little bit of a complicated one, but perhaps unsurprisingly, Melissa McCarthy is first cousins with Jenny McCarthy. Jenny is married to Donnie Wahlberg, whose younger brother is Mark Wahlberg. This means that Mark Wahlberg and Jenny McCarthy are in-laws, which naturally brings Melissa McCarthy into the family tree too.
