Christina Aguilera Sounds Off on Blake Shelton and Gwen Stefani Romance: 'They Deserve Happiness'

Christina Aguilera is totally on Team Blake and Gwen!

The 34-year-old singer, who will return to The Voice in season 10, weighed in on the burgeoning romance between fellow coaches Blake Shelton and Gwen Stefani. Both recently went through divorces, and Aguilera couldn’t be more ecstatic that the two have since found each other.

“I do know from my own personal experience how difficult divorce can be,” Aguilera told ET on Thursday, as she promoted her partnership with Verizon’s HopeLine. Aguilera’s divorce from Jordan Bratman was finalized in 2011, after more than five years of marriage.

“All I do know -- from knowing Blake from so many seasons past and holding hands with the guys from season one [and] knowing Gwen for even longer than that, going to each other’s kids’ birthday parties, etc. -- they’re great people,” the mother of two, who is engaged to Matthew Rutler, continued.

Aguilera had nothing but positive things to say about the new couple, making a point to emphasize the national attention they’ve been receiving recently.

“They deserve happiness, especially when you have to deal with a lot of the press crap and everything," she said.

And the rumor mill has been incessant. On Thursday, Shelton shut down a tabloid report that Stefani was pregnant with his child, tweeting in response, “To quote my friend @BradPaisley ‘The more they run my name down the more my price goes up,” and joking that he was “fertile.”

“I feel for them,” she said. “I know firsthand what that’s like, so good for them. Whatever makes them happy – they deserve it. Life is hard enough, right?”

Last week, ET confirmed that Shelton and Stefani were officially dating, and they were spotted holding hands at a CMA after party in Nashville on Nov. 4. Then on Monday, ET was on the scene for The Voice's first live show of the season on Monday, where the pair flirted when the cameras weren’t rolling.

When ET caught up with Aguilera, she explained that she's teaming up with the HopeLine program in order to spread awareness for domestic violence.

“I know first-hand what it’s like to have domestic violence in your life,” she said. “That’s why I’m proud to be working with HopeLine from Verizon to encourage people to take action against domestic violence.”

“There’s an easy way to help – you can get involved by purchasing an exclusive Verizon phone bundle at Walmart, to support HopeLine and the work of the Joyful Heart Foundation,” she added. 

Aguilera also previewed the next season of The Voice, and she’s hopeful that this time, she’ll prevail.

“We’ve already pre-taped next season – season 10’s blinds. We all have our teams. This could be the season, cross my fingers, that Team Xtina might take it,” she forecasted. “I’ve got some pretty great talents.”

The Voice next airs Monday at 8 p.m. ET/PT on NBC.
