Little Mix, James Arthur, Louisa Johnson and 5 After Midnight have been confirmed for Capital FM's Summertime ball.
Tickets for the 2017 concert at Wembley Stadium on June 10 are on sale now.
Louisa, who won The X Factor in 2015, said: "I’m so excited! I feel like Wembley is my home recently, I’ve been there a lot!
"It’s everyone’s dream to play Wembley, just to even sing there and soak up the atmosphere is amazing. It’s so cool."
And newly solo One Direction star Niall said: “I don’t know what it’s like on my own so we have to find that one out but I’ve done the Summertime Ball before, we played a few nights at Wembley Stadium and I’m looking forward to it, it’s going to be a great day.
“You get well looked after backstage, you more than likely get good weather – there’s something about Capital’s Summertime Ball that always has good weather!”
But he admitted his biggest ever solo gig would be daunting.
"No doubt about it, if you don’t get nervous there’s something wrong with you!" Niall confessed. "It’s like how can you not? You’re stepping out in front of 80,000 people, it’s going to be scary.”
Capital’s Summertime Ball with Vodafone will take place on Saturday June 10th 2017.
