Marvin Humes has been named as co-host of The Voice by the BBC.
The JLS member and Capital Radio DJ will join Big Brother presenter Emma Willis when the show returns for its third series in the New Year.
Humes told Digital Spy last month that he "wouldn't say no" to The Voice.
"I'm so excited to be a part of the new series of The Voice," said Humes in a statement. "I have always been a big fan of the show and love that musicians are given such a great opportunity to reach such a wide audience.
"I'm thrilled to be working alongside Emma and be part of a new team on The Voice. It's going to be even bigger and better with this new series. I can't wait to start."
The BBC's controller of entertainment Mark Linsey expressed his belief that Humes "is perfectly placed to encourage the acts through the competition".
Humes made a one-off appearance alongside wife Rochelle as guest host of This Morning just a few weeks ago, with 61.5% of Digital Spy readers saying that they thought the pair did a good job.
The Voice will return to BBC One in early 2014 with Sir Tom Jones, Kylie Minogue and will.i.am as coaches. The show's fourth coach is yet to be confirmed.
