Courteney Cox and David Beckham. One renowned for starring in one of the biggest sitcoms of all time. The other recognized globally as one of the true all-time footballing greats.

There's no denying that these two a-listers are two of the biggest names in all things celebrity. But I do have one question... What the hell are they doing in a hot tub with the two dudes from Modern Family?

And another question...

What the hell is Courteney Cox's hand doing? Well, keep scrolling to find out exactly what went down...

David Beckham is a footballing legend.

Okay first things first, let's do some introductions. Although admittedly, these two stars need none. David Beckham. We all know him. He's been a legend since he first began kicking footballs. He's scored countless goals for Manchester United, Real Madrid, and LA Galaxy. He also starred in 115 games for England making him the most capped English player in history after Peter Shilton.

He's also a legend off the pitch.

For as long as I can remember Beckham has been a huge icon. He's a role model for many, as well as a huge name in the fashion world.

Courteney Cox, on the other hand, made a huge name for herself on Friends.

Cox joined Jennifer Aniston (Rachel Green), Lisa Kudrow (Phoebe Buffay), Matt LeBlanc (Joey Tribbiani), Matthew Perry (Chandler Bing) and David Schwimmer (Ross Geller) for what became her most famous role, as Monica Geller on Friends.

She's also an avid Instagram user.

Courteney has been on Instagram for years, and she gives updates on just about everything in her daily life. Recently Jennifer Aniston signed up - and it's rumoured that Courteney was the one who prompted her to take the leap.

She recently posted a tribute to Jennifer Aniston.

Jen signed up to Instagram significantly later than her Friend's coworkers - but Courteney was more than willing to give her the welcome she deserved.

She made the comment under her first post.

Posting under Aniston's first-ever Instagram post, Courteney wrote:
Hi Jen, welcome to the social media world. It sucks. You're gonna love it.!

It's not just a Friend's reference.

It actually dates back to the first EVER Friend's episode when Courteney said almost the exact same thing to Jen.

So Courteney is a pretty big deal on Instagram.

As you can see, Courteney's kinda a big deal on Instagram. And with five million followers, most of her posts are being seen by her massive fanbase across the world. But then...

She posted this.

Yeah. I don't get it either. And neither does Jennifer Aniston, who commented:

But it wasn't just the picture that got people talking.

It was that hand. That god damned hand. Resting underwater on Beckham's lap. Just inches away from his... shaft? One person commented:
I see that hand Courtney. Victoria sees it too.
Another added:
Omg I noticed it too. Imagine Victoria looking at this picture with an eyebrow raised.

Some people aren't finding it too funny...

One person said:
Courtney keep your hands to yourself.
Another wrote:
If I was Victoria I would be fuming.

But what was actually happening...

Well, it would appear the photo was taken on the set on Modern Family.

Other stars were in the tub.

The main clue being fellow stars of the show, Jesse Tyler Ferguson and Eric Stonestreet, also being in the tub. And also a shot of Beckham and Cox reading their scripts for a new episode. It's certainly an all-star cast!

Beckham has since spoken out the photo.

Speaking about the whole debacle, Beckham told people to 'come on'.

He made a Friend's reference too.

In his response, Beckham wrote:
I mean come on itโ€™s Monica , Mich & Cam ๐Ÿ’— can it get any better.
Eric Stonestreet also commented saying he liked it! Whereas Jesse Tyler apologized for being gassy.

But I have another question.

Where was my invite? This hot tub party looks like the bomb. Let me in.
