The Voice

The superstar charmingly noted her long history with Blake Shelton, who even figures in her teenage diary!

Both singers want to win this season, and Shelton admits he has no problem competing with his girlfriend.

The singer revealed he'll be replacing Gwen Stefani in 2020 for the next season of the show, and he's got his eye on beating Shelton.

Gwen Stefani hit her button too, but this was a slam dunk...after a little argument.

The singer reveals that he is thankful that he did not win the show, because it gave him time to figure out who he was.

The teen delivered a version of Drake White's "Makin' Me Look Good Again" that had the couple sparring.

Let's go back to 1995 to sing Gwen Stefani's signature hit with No Doubt!

Now, it's love.

Some of the show's contestants and coaches have traded in baby faces for more sophisticated, mature looks -- and others haven't aged a day.

Those harmonies though!
