Donel will sing live to the nation for the second time tonight when The Voice’s top four acts compete in its final.
However, the 16-year-old appears to have booked a high-profile gig before the ITV talent contest has even ended.
Donel has apparently been asked to perform at The Queen’s Birthday Party, a star-studded concert being held to mark the monarch’s 92nd birthday.
Will.i.am let the news slip at a press conference for the semi-final, revealing it was Prince Harry who extended the invite.
“He showed me this letter... oh, am I allowed to say this?,” the Black Eyed Peas frontman said (quotes via The Sun).
“He got a letter from Prince Harry inviting him, requesting him, to perform at his grandmother's 92nd birthday.
“I was like 'woah, get the hell out of here, bro’. He's only had three performances on TV and he gets that. It’s amazing.”
Fellow coach Olly Murs appeared shocked by the news, reacting: “At least we know they watch the show now!”
The Queen’s Birthday Party takes place at the Royal Albert Hall on Saturday 21st April, with Her Majesty and other members of the royal family due to attend.
It will feature celebratory performances from big names including The Voice stars Sir Tom Jones and Kylie Minogue.
Other stars on the bill include Shawn Mendes, Craig David, Sting and Shaggy.
The concert will be broadcast live on BBC One and BBC Radio 2.
Donel is the last remaining act on Will’s team ahead of The Voice final.
The live show airs tonight at 8.30pm on ITV, when viewers will decide who win.
