He said he was "thrilled" to be in the line up.

Life is a Rollercoaster singer, Ronan Keating, is up next on stage.

Having grown up with Chelmsford on my doorstep, it has always been hard to believe that people who are genuinely world-famous could be chilling in the park a short drive away.
But that is exactly what has happened over the years, thanks to Hylands Park’s popularity as a festival destination.
Crowds at the venue have seen big names including Oasis, Jay-Z and Rihanna perform here in years gone by.
I still remember the excitement of watching Justin Bieber arriving by helicopter at V Festival in 2016.
And who can forget when Beyonce spent almost £1,500 at the Chelmsford branch of chicken restaurant Nando's?
Today’s acts will only add to the legacy Hylands Park has in Essex.

"I’ve never been to Essex or Chelmsford - it’s very beautiful," says Karen.
“The acts so far have been wonderful."
She is most excited to see headliner Bryan Adams later, she tells us.

We cannot wait to see the selfie results on Jeremy's TikTok account later!
As we head into the evening, here is a reminder of which acts are due on the main stage:

Image source, Nadira Tudor/BBCEddie Bodsworth, 58, has travelled over from Fairford, Gloucestershire.
He mainly came to see Stereophonics perform earlier.
"[It's] my first Radio 2 in the Park and my first time in Essex," he says. "I think it’s a stunning place and setting."
We could not agree more, Eddie.

BBC Essex's Matt Mackay was just nipping to the loo when he was approached by a man looking for directions.
That man was no other than tonight's headliner Bryan Adams.
This is not how we expected to tell you Bryan Adams has arrived in Chelmsford, but... Bryan Adams has arrived in Chelmsford.
If you're not in Chelmsford today, one thing you should know is Jessie J knows how to interact with a crowd.
She speaks so openly to her audience, getting them laughing, cheering and singing along.
The audience is nothing short of captivated by the singer, even more so when she brings her young son on stage to sing his own rendition of Happy Birthday along with the crowd.
A chorus of "awwws" ripple across the audience. So cute.
Jessie J tells the crowd of her breast cancer surgery 11 weeks ago.
"The last show I did, I had no idea what was going to happen," she says.
"I'm still very much in the recovery process. I'm definitely not ready for back bends. Well, I am, but my doctors are like: 'Calm down girl.'
"I'm so grateful to be here... I'm so grateful to see so many of you singing along after all these years.
"It truly feels like I'm a little kid still doing what I love."

The pair were childhood best friends and tied the knot two years ago.
“We are making memories," says Tracy.
There is a lovely feeling at the start of Jessie J's set as she opens with an acoustic version of her song Domino.
She asks the crowd: "Are you ready to have some fun?"
The crowd is singing along with her as she performs in a stunning and glittery silver outfit.

Jessie, 37, is a Brit Award winner and has sold more than 20 million records with global hits including Price Tag, Domino and Bang Bang.
The Essex singer revealed her early breast cancer diagnosis at the beginning of June and received widespread support from fellow colleagues for sharing her experience.

Image source, Elliot Deady/BBCGlyn Boallman and Gary Abraham are among a group of eight friends who have come from Teignmouth in Devon.
All eight are wearing matching outfits.
Mr Boallman admitted they wore the same shirts to Radio 2 in the Park in Preston last year: "Nobody gets lost, you see!"
Image source, Lauren Carter/BBCAhead of her set at 17:00 BST, Jessie J said this felt like a homecoming gig.
"All my family are out there, some childhood friends," she said.
"As we got closer and we went through Romford, where I grew up - I was born in Seven Kings - this is my ends."
She added she had fond memories of when she performed at Hylands Park during V Festival on numerous occasions.
"When you're born and raised in Essex, that is something that stays in your blood.
"It never leaves, I can feel my accent getting stronger as the day goes on."
Image source, EddieBlizzard/BBC Weather WatchersIt's fair to say we've had some horrible weather this past week, so festival-goers might be wondering how the rest of the day’s looking.
Well, it's good news.
It's still looking warm and clear, and temperatures should only drop to about 18C this evening towards the end of the performances.
Be sure to stay hydrated in between your singing and dancing!
Image source, Shivani Chaudhari/BBCThe crowd seemed to love the party vibes from Kid Creole & The Coconuts.
The band's trumpet symphonies were spreading waves of positivity across Hylands Park.
"Thank you, music lovers," Kid Creole shouted as he did the conga on stage - legendary moves.
