US singer Jennifer dazzled in a black dress and cape as she braved the cold and rain in Manchester at the show's launch on Tuesday evening (18 October).
Jennifer was joined by fellow newbie Gavin Rossdale, Voice UK veterans Sir Tom Jones and Will.i.am, and hosts Emma Willis and Cel Spellman.
The new lineup comes as The Voice UK makes a landmark move from the BBC to ITV. The sixth series of the singing competition will air on the commercial channel in early 2017.
After being announced as a coach, former American Idol star and Oscar winner Jennifer said: "I couldn't be more excited to join the amazing panel of coaches on The Voice UK!
"The UK has always been so supportive of me since the beginning of my career so I'm really looking forward to sharing my point of view with the contestants and especially Team JHUD."
She added: "Discovering new artists has always been important to me and the UK has no shortage of talent, so I can only imagine what this experience will be like for everyone involved.
"I can't wait to get going and start developing each individual's own sound!"
British rock musician Gavin, who was previously married to Gwen Stefani, was also announced as a coach last month.
Speaking about his new job, he said: "I am so thrilled to be joining The Voice UK.
"I have always been extremely proud to fly the flag for British rock music and I can't wait to join this incredible panel and help discover some new talent."
We. Can't. Wait.
