This is it, we are set for lift off. This crowd is buzzing...

As far as outfits go...

The IBF heavyweight world title is held up behind Charles Martin as his name is called. He looks relaxed, shaking his shoulder and then bopping on the spot to raise his right hand.

Across the ring AJ is fist bumping his team. They all have the words "stay hungry" written on the back of their t-shirts, it's his mantra. Time to tuck in...

BBC Sport's Ben Dirs is ringside...

Of course, when Michael Buffer says this, you know it's on: "And now the officials are ready, the fighters are ready, boxing fans are you ready? For the thousands in attendance and millions watching around the world, ladies and gentleman, LETS GET READY TO RUMBLE."

"He is massive isn't he?" says a colleague.

Yes, yes he is. But what's that saying? The bigger they are the harder they fall.

Not tonight, this is his time surely?

Gerald Whalen: I truly believe there is more talk in the United States about #JoshuaMartin, external than there is for #PacquiaoBradley, external.

Over to Star Spangled Banner we go... "oh say can you see."

No emotion on the face of Charles Martin, this ain't no Olympic podium.

We move to the national anthems and Anthony Joshua is still walking around as God Save the Queen blares out. There's a lot of singing, a Union Jack, all that's missing is a bull dog.

Jessica Ennis is in the house though and she's pretty much the pride of Britain isn't she?

Haven't Liverpool got a game tomorrow Jon? Get to bed...

Charles Martin is throwing lefts and rights as he comes to the ring. This is not the behaviour of a prince but then this is boxing after all.

Martin steps over the top rope like Andre the Giant. It always freaks me out when someone is big enough to do that.

"And now, coming to the ring, from the United States of America, the undefeated heavyweight champion... Prince... Charrless... Martin."

Michael Buffer is on form and here comes the champion wearing a cape and crown. Boxing meets WWE. 

James Foster: I love heavyweight boxing - nothing else compares to it, the fact that at any time one punch can end it all. Joshua in the 5th.

And we get our first glimpse of the big man as he enters to Puff Daddy and The Notorious B.I.G - "Mo Money Mo Problems".

This is electric, the smart phones are out wherever you look as he dances into the ring with his white robe on. It looks an expensive number, not the type of thing you'd sit and eat your cereal in.

The O2 Arena sings: "Oh Anthony Joshua, oh Anthony Joshua..."

Michael Buffer lets rip: "Coming to the ring it's AJ, Anthony Joshuaaaaa"
