Blake Shelton Sad Gwen Stefani is Leaving 'The Voice' [VIDEO]: Singer Exiting Show Next Week

Gwen Stefani will be leaving The Voice following the Season 9 finale next week, with Christina Aguilera returning for Season 10. Stefani's fellow coaches will miss her, but boyfriend Blake Shelton will obviously miss her the most. The country star questioned why there can't be a fifth coach on show.

The Voice coaches chatted to Extra about Stefani's exit from the show.

The No Doubt singer will leave the singing competition show after the finale last week and will focus on her music.

Stefani was asked who she will miss the most, jokingly stating, "I wonder…" She added, "It’s the combination. It’s the chemistry."

The blonde singer also admitted, "I’m already so devastated that I think I only have like three more looks to do, three more outfits. And that I’m not going to be around these guys. It’s hurting me."

Shelton weighed in on his girlfriend's departure, stating, "I don’t want Gwen to not be on the show – why can't we have a fifth coach?"

Stefani will definitely be keeping busy, putting out an album and performing.

The singer adds she is excited to perform on NBC's New Year's Eve With Carson Daly.

Gwen told the interviewer, "I cannot wait for that. I have not performed on New Year's Eve in a long time. It’s gonna be awesome."

Stefani and Shelton confirmed they were dating last month, after weeks of dating rumors circulating.

The "Used to Love You" singer filed for divorce from Gavin Rossdale in August after almost 13 years of marriage. They finalized their divorce in October.

There were reports that the Bush singer may have been having an affair with the nanny of their three sons for several years.

Shelton filed for divorce from Miranda Lambert after four years of marriage, making the split announcement two weeks before Gwen's divorce news was reported.
