No Doubt has released hit albums over the past few years, but Gwen Stefani revealed she was not a fan of one song they released.

Stefani founded No Doubt in 1986 in Anaheim, California, along with Tom Dumont, Tony Kanal and Adrian Young. They officially marked their debut in 1992 with the "No Doubt" album and continuously dropped new materials afterward.

Gwen Stefani Says One No Doubt's Song Makes Her Want To Puke

Twenty-four years after No Doubt released its single, "Ex-Girlfriend," from its "Return of Saturn" album, Stefani sat for an interview with KROQ's Klein & Ally during an Audacy Check-In during which she reflected on her impression of the song.

"I can't listen to a lot of the songs because they speak so clearly to me. And it's like you have regret and mistakes you've made," she said. "Most of the songs are about that. If I do 'Ex-Girlfriend,' even when I say it, I almost throw up in my mouth because...it's just like, 'Oh my God.' It just brings you right back."

"Ex-Girlfriend" was a moderately successful track of No Doubt, reaching the top 40 list of different charts.

The track may be heard by fans again as No Doubt is set to reunite at this year's Coachella festival. It will be the first time the bandmates will share the stage together following their permanent hiatus in 2013.

"I don't remember them, no, not at all. I don't! I think I'm going to have to learn probably like, eight or nine [songs]. One of the first songs I ever wrote was called 'Different People;' we're doing that," she said about their reunion on Jimmy Kimmel Live!

Gwen Stefani Expresses Her Excitement

Elsewhere in her KROQ interview, she looked back at No Doubt's humble beginnings and how they made it big.

"We weren't doing it to make it. We were doing it because it was procrastination from school and everything else in life," she disclosed. "It was pure passion, you know? We knew we were doing the kind of music that no one would really...it was very, like, us. It wasn't anything that was 'happening' at the moment, so where do we fit in? We didn't."

After working hard, No Doubt established a huge fanbase whose members still supported them after their hiatus.
