Gwen Stefani got choked up on Wednesday's pre-taped The Voice, following a report that her ex-husband, Gavin Rossdale, had an affair with their children's former nanny.
Stefani, who serves as a team leader on the NBC reality competition series, was forced to choose which of her singers -- Korin Bukowski, Ellie Lawrence, Regina Love or Viktor Kiraly -- she would save after it was revealed that America spared Jeffery Austin and Braiden Sunshine.
The No Doubt front woman was visibly emotional when making the decision. "Honestly, I am so blown away by this whole experience, I cannot believe," she said, nearly tearing up. "You guys are saving me, you know, you are saving me."
Continuing to gush over her team, Stefani added, "I love you guys, watching you blossom right before my eyes, having my influence on you is such a gift."
Making the choice of who to cut was clearly hard on the 46-year-old singer. "I only get to save one of you guys and that is totally upsetting," she said. "All can do in this crazy moment is follow my heart and think of the person I am going to be able to help the most."
Stefani ended up saving Bukowski and sending home Lawrence, Love and Kiraly.
This was Stefani's first appearance on The Voice since news broke of an alleged three-year affair between Rossdale and the family's nanny, Mindy Mann.
ET found several photos of the 50-year-old rocker's alleged mistress, and noticed that she dresses a lot like Stefani. Check out the shocking similarities.
