Gwen Stefani returned to The Voice on Tuesday to continue mentoring boyfriend Blake Shelton’s team, and the two shared several sweet moments, including when Blake told Gwen he would “share” the victory with her if a singer from his team won.

“You took Craig Wayne Boyd and did all your stuff that you do and then you threw him back out there to me,” Blake recalled of the season seven champ, who went back and forth between Team Blake and Team Gwen before winning the season for the country crooner. “I won because of you.”

“I didn’t even share that with you,” he told Gwen. “If I win this season, with you as my mentor, I will share the victory with you.”

This week, the pair teamed up to coach two of Blake’s singers -- 27-year-old Brittany Kennel and 20-year-old Trey O’Dell -- through the final battle round. The singers impressed Blake and Gwen with their powerful voices, though the couple had to give them a few pointers in regards to onstage chemistry.

“Once we said ‘Get rid of the microphone stands, they pretty much sang right to each other’s faces, and the mood of the lyrics started to really come through,” Gwen noted.

“Whoever can connect with this song is gonna win this thing,” Blake mused after the rehearsal session. “This is going to be a tough decision for me.”

All four judges were impressed by the pair’s performance of Fleetwood Mac’s “The Chain,” including Christina Aguilera, who made an impressive comparison between Brittany and Gwen’s voices that Blake noted during the blind auditions.

“You have that really fast vibrato,” she said, before turning to Blake and noting, “There’s something Gwen Stefani about her.”

“That’s your girlfriend!” Adam Levine interrupted, leading to playground-level catcalls from him and Christina.

Ultimately, and perhaps unsurprisingly, Brittany won the battle, but there were no hard feelings on either side, as Christina was quick to use her final save and snap up Troy for her own team.
