Louis Tomlinson is set to return to the stage for the first time since the tragic passing of his sister Félicité, 18.
His younger sister died suddenly on March 14, leading Louis to pull out of a scheduled Comic Relief performance just two days later.
Now the former One Direction singer has confirmed his comeback performance at the Free Radio Hits Live show in Birmingham on May 4.
Free Radio breakfast host Ben Hanlin, who will be presenting the concert alongside Celebs Go Dating star Sarah Jane Crawford, said they were "really grateful" to have the pop singer on board.
Louis, 27, will join the likes of Ellie Goulding, Zara Larsson and The Vamps at the concert.

The One Direction star had been scheduled as one of the headliners of the live charity event in March.
It was expected Louis would perform new single Two Of Us which was written about his mother Johannah, who died from leukaemia in 2016.
He was seen for the first time since his younger sister's death towards the end of March to celebrate his twin sisters' birthdays.
The social media influencer was found dead in her London flat on March 13 after suffering a suspected heart attack.
And while her other siblings, including Daisy and Lottie, have been sharing tributes to Félicité on social media, One Direction singer Louis has kept his head down as the family deals with their horrific grief.
But he spent the day with sister Daisy, who celebrated her 16th birthday along with twin sister Phoebe.
