The pop stars keep coming.

Justin Bieber and model wife Hailee Bieber are among the famous faces in situ at Allegiant Stadium.

Feeling pumped for Usher at half-time no doubt.

Andrew Priestley: Although it happened early in the 2nd Quarter with the score at just 3-0, that Pacheco fumble-turnover could ultimately define this Super Bowl. The 49ers are suffocating the Chiefs and Mahomes had just blown it wide open. Momentum gained and then immediately lost.

San Francisco 49ers 10-3 Kansas City Chiefs

Harrison Butker makes no mistakes from 28 yards to finally get the Chiefs on the board - with just 23 seconds left in the half.

Patrick Mahomes tries to wriggle forward again with his receivers covered, but he's just smashed by Arik Armstead at the line of scrimmage and the Chiefs lose the chance to find the end zone.

They'll have to take the field goal.

Confirmation! Dre Greenlaw is out for the remainder of the game. Huge blow for the 49ers defence. The linebacker looks to have injured himself running onto the field of play. His Achilles is apparently the issue.

Inside the final 90 seconds and the Chiefs finally getting something going as the look a bit more fluid in the hurry-up offence, getting a couple of first downs and marching inside the red zone.

Andy Reid takes a time out with the ball on the San Francisco 11.

It's taking every ounce of effort Patrick Mahomes has got just to keep the chains moving here, as he just about evades Nick Bosa to fire a ball to Justin Watson.

In three years in the NFL, Jauan Jennings has not even attempted a single pass.

Then the 49ers ask him to let fly in the sport's biggest game and he registers a touchdown pass. That's why we love this sport.

The Chiefs are all over the place here - strange for a team who played in last year's Super Bowl but they're a bit ragged, making mistakes and giving away penalties.

Defensively they've been pretty good overall, but that 15-yard penalty helped put the Niners in range to score their touchdown.

Offensively it's been a mess, with Patrick Mahomes unable to breathe back there under intense pressure. They need to somehow start turning this around quickly.

So, just to recap.

Brock Purdy & Patrick Mahomes combined TD throws: 0

Jauan Jennings TD throws: 1

Funny old game!

Jason Bell, former cornerback for the New York Giants on ITV: "A momentum changer. Give Christian McCaffrey space and blockers in front of him... and we knew this game would be about CMC. That was orchestrated to perfection. That was the play they had to have in the moment they needed it.

"It's what might fire Patrick Mahomes up. The Chiefs have to get points before the end of the half so let's see what they do."

Osi Umenyiora, former defensive end for the New York Giants on ITV: "A little bit of trickaration from Kyle Shanahan. And yes, that is a word! An outstanding play call."

It's a Kyle Shanahan special. It's doing the unexpected, it's being aggressive but also being creative - getting the ball to your best playmaker by disgusing it and sending it the other way.

Ryan Fitzpatrick, former NFL quarterback, on Sky Sports: The lack of composure from the Chiefs is shocking.

Andrew Priestley: All the pre-Super Bowl focus surrounding the Chiefs has been on Mahomes, Kelce, Reid and Taylor Swift. But the most important piece of the puzzle for them is actually DC, Steve Spagnuolo. If the Chiefs can hold the 49ers to <20 points, they’ll win. Simple as that.

The Chiefs are losing their discipline right now with L'Jarius Sneed flagged for a petty slap in the face of Brandon Aiyuk - it's just pressure from things not going their way so far.

You can't do it though, especially right in front of those in black and white stripes.

Defences have been firmly on top so far - and they do say defences win championships - so which team will this favour?

Finally a shot of Taylor Swift on the big screen and she was ready for the moment. Picking up a cup of something 'see-through' before chugging it all in one go and slamming the cup down. Mixed response from the crowd.

Deebo Samuel takes a tough catch over the middle, then takes a couple of loud, bone-crunching hits but hangs onto the ball to move the sticks again.

Jason Bell, former cornerback for the New York Giants: How do you think you get to a championship? By playing defence! These teams are very prepared and they understand exactly what they have to do.

They are targetting the quarterback to make sure they cannot get going and taking away their best offensive weapons. This is what you have to do to stop them.

It's fascinating.
