During the event, Rossdale gave his first interview following rumors that he allegedly cheated on the No Doubt frontwoman with the family's nanny, Mindy Mann, for three years. Stefani reportedly learned of the affair after allegedly discovering texts containing nude photos and plans to meet up on the family iPad.

Though the 50-year-old kept quiet about Stefani, he wasn't shy when chatting to People about the former couple's three kids together -- Kingston, 9, Apollo, 7, and Apollo, 20 months.

"The boys interact so well, and they truly love each other," Rossdale explained. "They are so sweet and protective of each other, and they have little dance parties. I am always on the lookout to see what they are doing next and how they are working their naughty habits!"

Rossdale noted that he's focusing on his band's 2016 world tour and new album, but is scheduling everything around his kids' schedule.

"My children come first," he revealed. "I am taking the boys on a special trip Dec. 26. Where we are going is a big surprise!"

He also chatted about his passion for the honorary sport. "I play tennis in bits and pieces throughout the year," he said. "For me, it's a big sport. And I play when I can."

Earlier this month, Rossdale was spotted wearing his wedding band while heading to a local tennis club in Los Angeles, just one day after the affair reports surfaced. Even though Stefani's relationship with Shelton is heating up, she's still legally married to Rossdale, as ET previously reported. The two filed for divorce in August, and are waiting for a judge to officially sign off on the documents.

A source close to Rossdale told ET that "he's bummed that the marriage is ending, but he wants Gwen to be happy. If being with Blake makes her happy, so be it."

On Wednesday, Stefani got candid about her divorce in an interview with The Tommy Show on 94.7, where she said she wished her divorce from Rossdale "didn’t happen."

"I wish that all this wasn't happening," Stefani said. "But at the same time, I feel like it was part of my life journey."
