Louis Theroux and Justin Theroux

So you'd think the last name would be a giveaway, but it's surprising how many people don't make this connection.

The documentary maker and actor are actually first cousins. And the two are so close that Louis told The Guardian that if they ever make a movie about him, he'd like Justin to play him.

Dakota Johnson and Antonio Banderas

The Gossip Girl star and Coach Bolton from the High School Musical films are related, and actually have been for quite some time.

Johnson married Blake's sister Robyn Lively back in 1999, meaning the two are brother- and sister-in-law.

Once you read that they all have the same last name this will make total sense. But if you've watched (and loved) Schitt's Creek, the father Johnny, son David and waitress Twyla are all family in real life.

Yes, Twyla and David are siblings.

Julia Roberts and Emma Roberts

Emma Roberts was born into one of the most recognisable families in Hollywood. Her aunty is Academy Award-winning actress Julia Roberts and her father, Eric Roberts, has been nominated for an Oscar.

Jessica Capshaw and Steven Spielberg

Jessica Capshaw is known for playing the role of Arizona Robbins in Grey's Anatomy. What most people might not know, is that her stepfather is Academy Award-winning filmmaker, Steven Spielberg.

Kate Hudson and Wyatt Russell

Kate Hudson and Wyatt Russell are half-siblings. Russell, who has starred in Black Mirror and 22 Jump Street, is the son of Kurt Russell and Goldie Hawn.

Hudson's mother is Hawn, which means Russell is the younger half-brother of both Kate and Oliver Hudson.

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.

Mamie Gummer and Meryl Streep

Mamie Gummer is known for her recurring role as Nancy Crozier in the political drama, The Good Wife. But something many wouldn't know is that her mother is the fantastic Meryl Streep.

Ashlee Simpson and Tracee Ellis Ross

Ashlee Simpson not only grew up with a famous sister, Jessica Simpson, but she also married into a famous family.

Back in 2014, Simpson married actor and musician Evan Ross. His sister is Tracee Ellis Ross and their mother is the iconic Diana Ross.

Elle King and Rob Schneider

Another surprising connection here. The real name of the singer of hit single Ex's and Oh's isn't Elle King, it's Elle Schneider. Her dad is the hilarious actor and comedian, Rob Schneider.

Ron Howard and Bryce Dallas Howard

Yes, another pair of related celebrities that we probably should've known about considering the last name. However, it came as a surprise that American filmmaker Ron Howard's daughter is the actress Bryce Dallas Howard.

Luke Wilson and Owen Wilson

For many, this will come as no shock, but for others, this might be news to you.

Yes, Owen Wilson and Luke Wilson are brothers.

Alfie Allen and Lily Allen

Probably the biggest surprise of all.

The Game of Thrones and Jojo Rabbit actor, Alfie Allen, is the younger brother of pop sensation Lily Allen.

Woah.
