If you're a "Parenthood" fan, you know the Braverman clan is the most tight-knit family on TV -- they laugh, they cry, they solve each others problems. But did you know the "Parenthood" cast is basically a family too?

Here's the proof:

Mae Whitman (Amber Holt) and Miles Heizer (Drew Holt) are real-life roommates.

“We’re definitely unusually close, just as far as human beings go,” Whitman told BuzzFeed. “Miles is definitely my best friend.”

Even better, they're in each others phones as "Mae Blood" and "Miles Blood."

Lauren Graham, Mae and Miles' TV mom, really wants to be their real mom ...



"This is my son, Miles. I'm the mom, he's my son," Whitman joked in an interview with Zap2it. "He's my son! You're not even in wardrobe! What are you doing?" Graham joked back, before Heizer said, "You can both be my moms."

... And she's all about sending them loving tweets.

Dear Shirley:

I'm nothing without you.

Love,

Laverne — Lauren Graham (@thelaurengraham) October 22, 2013

Graham's onscreen ex-fiancee Jason Ritter is part of the gang, too.



"Because I started four years ago with them, Lauren, Mae [Whitman], Miles [Heizer] and I all sort of stayed in touch and became like a little family," Ritter told HuffPost TV.

Sam Jaeger and Erika Christensen are bummed out that Joel and Julia are separating ... mostly because they love working together so much.

I worked all day with @Sam_Jaeger and didn't take any pictures for you 'Hoodrats, but he's still as handsome as ever. — Erika Christensen (@ERIKAjaneC) October 12, 2013

Xolo Mariduena, who plays Victor, isn't above guilt tripping his TV parents ...

I'm still team #Joelia, but wouldn't mind if @Sam_Jaeger & @ERIKAjaneC sent victor to Hawaii to ease the pain #GuiltTrip — Xolo Mariduena (@Xolo_Mariduena) January 25, 2014

... And it certainly looks like Savannah Paige Rae (Sydney) and Tyree Brown (Jabbar) are BFF.

Mae Whitman and Joy Bryant are all about TV-related late-night phone calls.



"You'll really never find anyone cooler than Joy [Bryant]," Whitman told Rolling Stone. "Sometimes we call each other late at night just to recap 'Chopped' episodes."

Monica Potter and Peter Krause may not be married in real life, but they're still best friends.



Did we mention they're obsessed with each other?



"I’m extremely honored to be a part of this family," Whitman told Rolling Stone. "I hope this show goes on a million years so I can grow old with these clowns."
