Celebrities You Didn't Know Were Related

With all due respect to Kevin Bacon, you don't need his films to connect everyone in Hollywood. You don't even need six degrees. They're all related!

Whether through blood or marriage, many celebrities all seem to be part of the same family tree. Kendall Jenner and Gigi Hadid aren't just pals; they've also both had Brody Jenner as a brother. Meanwhile, their model friend Haley Baldwin is part of an ever-growing clan that currently overlaps with half of Hollywood.

Cameron Diaz and Lionel Richie also happen to be, somewhat improbably, part of the same family. Casey Affleck counts both Jennifer Garner and Joaquin Phoenix as in-laws. And Stanley Tucci, Emily Blunt, and John Krasinski are probably planning a family BBQ for the weekend.

Seriously, it's complicated... not to mention a teensy bit inbreed-y.

Cameron Diaz & Nicole Richie
Relationship: Sisters-in-law

Richie reportedly played matchmaker for Diaz and Benji Madden. The couple, who wed in 2015, frequently hang out with Richie and her own Madden twin hubby, Joel. Throw in Richie's own famous family members, pop star pops Lionel and budding "it" girl half-sister Sofia, and you've got a crew that probably rolls out the red carpet for Sunday dinner.

Casey Affleck & Joaquin Phoenix
Relationship: Brothers-in-law

Here's a fun one: In addition to being the younger brother of Ben Affleck and counting Jennifer Garner as a sister-in-law, the Manchester by the Sea star is also part of the large Phoenix family... for now, anyway. The actor is separated from Summer Phoenix, the sister of Joaquin (with whom he worked on To Die For and the controversial mockumentary I'm Still Here) and the late River Phoenix.
