The players are being announced individually to get their cheers from the crowd.
They're all wearing Arsenal shirts with "champions 25" on the back.
Of course, every player is wearing their winners medal.
Arsenal legend Alex Scott is on the stage and has announced the players are making their way out.
Here we go!
Chloe Kelly may well have laughed if you'd told her before Christmas she'd have a Women's Champions League winners medal around her neck.
"I said I was coming to this club to find happiness with football and I have a medal round my neck," an emotional Kelly told BBC Sport's Jo Currie. "Every day that I come into the club I'm smiling. They put the smile back on my face so I will forever be grateful for that.
"I took a step to try and make things better for myself and I'm grateful for the people around me that supported me to take that step. This one is for everyone that helped me do that."

Friends Bill Tasselli from York and Daisy Goodhand from Lincolnshire stayed over last night in St Albans and were at Armoury Square "nice and early".
Daisy said they made the journey "just to be here with everybody, our favourite people...and to see the girls as well".
"I am so glad they put this on and that so many people are here, because it’s testament to what we’ve been doing all season," she added. "It may go under the radar sometimes but this is what we do every week. We show up in our thousands no matter where it is and the Arsenal squad know that and we know how much they appreciate it, so we weren’t going to miss this for the world."
I can see the trophy!
Some lucky fans are getting to have a photo with it.
Memories to last a lifetime.

What a game! What a result from how this season started! These girls deserve all the admiration and today is for every Gunner in the world. The flag hanging from my window has never blown so proudly!

Imagine having two two-time Ballon d'Or winners in your team but in Aitana Bonmati and Alexia Putellas, Barcelona have just that.
This is just a snippet of the talent Arsenal had to overcome.
Is there anything better than watching your team win the biggest trophy of them all?
I don't think so!
We are live!

The BBC’s Briohny Williams says she recently saw the players arrive at the Emirates and head into the back of the stadium to prepare for their big moment – lifting the Champions League Trophy.

Fan Kate Sheard told the BBC: "We were in Lisbon, we got back at half past one this morning, and now we’re outside the Emirates to see the girls lift that trophy, because we saw it in Lisbon so we’ve got to see it in London today.
"I’m so proud. We followed them all over Europe this season… and we actually beat Barcelona and we’re now champions of Europe!"
Just saw a replay of Stina Blackstenius' winning goal again.
A moment I'm sure you Arsenal fans have watched countless times.
History.

I was right there at the stadium watching the seemingly neverending celebrations on the pitch. I'm back home now and feeling every bit of it, so I'm leaving this one to the many Gooners who couldn't be there on Saturday.

I missed my flight, it was absolutely worth it. I went out with the girls after, all my old teammates were there, my old manager Vik Akers. They were all so respectful of what we did but now it is their time.
The fans standing at the front of the crowd have been there since 06:00 BST this morning to make sure they get the best view of their idols.
Now that is dedication!
Arsenal's Beth Mead speaking to BBC Sport on the way to the airport: "The voice has gone. There was a lot of singing and dancing but it was well worth it.
"Every single person in that room enjoyed themselves. It was an amazing night with the team and we loved it with our friends and family too."
On if the achievement has sunk in yet: "Not really, still trying to get it to sink in. I think that will take a little while."
