The six friends at the heart of the show were relatable, sweet, and loyal to one another.

Two friends in particular stood out as having an especially close bond: Monica and Rachel.

Over the course of the show’s 10 seasons, the pair got closer and closer.

Although they had their arguments, these two pals showed us just how special a best friend can be.

Here is the truth about the relationship between Rachel and Monica on “Friends.”

The pair clearly did everything together, with Rachelspending Thanksgivingat Monica’s house and them evengoing to promtogether.

She’d never met Monica’s friends, and she clearly hadn’t seen Ross since high school.

To which, Monica added, “Who wasn’t invited to the wedding.”

It’s always awkward when old friends drift apart.

Instead, they quickly fall right back into being best friends.

Joey nonchalantly replied, “It’s fine.

You’re at Joey’s,” and he dropped some of his own food on the floor.

She’s a bit of a control freak, after all.

Yes, these two could be pretty conniving.

Over the years, they came up with tons of schemes.

Monica putting eye drops in Rachel’s eyes

Rachel helped Monicacome up with a planto seduce Chandler and then embarrass him.

Another conniving plan came in Season 3 when Rachel and Monica babysat Ross' son, Ben.

Again, this plan didn’t exactly turn out as planned, as Ross caught on pretty quickly.

Luckily, Monica always knew how to do what was best for her best friend.

Like a true best friend, Monicaheldher down and gave her best effort to get those eye drops in!

I make the decisions and I say, ‘No.'"

Monica knew that Rachel would only get hurt if she pursued Ross again.

It’s clear that Monica was always there for Rachel even when Rachel didn’t want her to be!

After all, these two lived together and had a ton of history.

Phoebe, after all, had fewer connections to Monica and Rachel and the rest of the group.

I just always assumed Phoebe would be the one to go."

It’s clear that Phoebe often felt a little excluded.

She later added that “no one ever listens to anything I say.”

It’s hard being a third wheel in a strong friendship.

Rachel, who was in denial about having to move, failed to pack until the last minute.

Things quickly escalated, and Rachel and Monica had a huge fight.

They argued about all of the ways the other was a bad roommate.

It’s clear that Rachel and Monica absolutely loved living together, even if they had their little spats.

Rachel and Monica were always willing to go the extra mile for the other one.

Rachel and her baby in “Friends”

Rachel also helped Monica out bywaitressing for herwhen she was trying to impress a potential restaurant owner.

Even though the evening didn’t exactly go to plan, Rachel was 100% there for her friend.

As the theme song goes, “I’ll be there for you.”

And these two friends were always, always there for each other!

In fact, Monica was always super supportive of Rachel throughout her relationship with Ross.

Monica was clearly thrilled, screaming, “Oh my God,” over and over again.

When Rachel found Ross’ pros and cons list about her, she was devastated.

While Monica didn’t take sides in their argument, she was totally there for her friend.

Still, it was clear that Monica wanted Rachel to forgive Ross.

In other words, Monica was the biggest Rachel and Ross fan out there!

“Here is a book of poetry that I know Monica loves,” she said.

Phoebe clearly saw how much being Monica’s maid of honor meant to Rachel.

This was exactly the case for Monica and Rachel.

When the baby arrived, Monica could not have been more in love with her niece.

Monica, as usual, was totally supportive and helped Rachel through her journey into motherhood.

And we have to say, it was all seriously sweet.

Ross explained that they were deliberating between two names.

“Take it,” Monica said, despite initially being hesitant to tell Rachel.

“She’s clearly an Emma.”

Rachel replied, “Oh, honey, but you love that name.”

Monica responded, “Yeah, but I love you more.”

You really can’t beat the power of friendship!

But, at the end of the show, both characters were preparing to go their separate ways.

While they were both happy about where they were headed, it was hard for them to say goodbye.

In a touching scene in the series finale, Rachel took Monica aside.

No one has been more like a sister to me."

Monica replied, “I know what you mean.

You’re like a sister to me, too.”

After meeting on the set of “Friends,” Cox and Aniston quickly formed a strong bond.

As Cox told TV Week (viaE!

Aniston also gushed about their friendship, telling More magazine (viaE!

News), “She’s extremely fair, ridiculously loyal, and fiercely loving.”

The pair have remained in touch since the show ended.

Cox was at Aniston’s weddings to Brad Pitt and Justin Theroux, and they apparentlytake lots of vacationstogether.

When Cox got divorced, Aniston was there for her.

Cox told TV Week, “Jennifer has been amazing for sure.”
