Gwen Stefani says she can't listen to some No Doubt songs because of the memories they hold.

The 54-year-old spoke about her time in the band and their upcoming reunion at Coachella during an appearance on the "Audacy Check In" podcast.

"I can't listen to a lot of the songs because they speak so clearly to me," Stefani said. "And it's like, you know, you have regret and mistakes you've made. Most of the songs are about that."

There's one song in particular that Stefani finds hard to revisit because it makes her feel sick: "Ex-Girlfriend," the lead single off No Doubt's 2000 album "Return of Saturn."

"If I do 'Ex-Girlfriend,' even when I say it, I almost throw up in my mouth," Stefani said. "Because it's like, I just know exactly where I was at in that moment to write that song, and what I know now. It's just like, 'Oh my God.' It just brings you right back."

The musician also shared that "the most satisfying thing" she's ever done in her career is songwriting because it helps her reflect and learn about herself.

"Songs are weird because it's not a lot of lyrics. It's not like you're writing a book, you know what I mean, or even a paragraph," Stefani said.

No Doubt is set to reunite for the first time since 2015 during the Coachella festival in April.

Earlier this month, Stefani told Jimmy Kimmel that the band hasn't started rehearsing for their Coachella gig yet. She also shared that she doesn't remember the lyrics to some of their old songs.

"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," Stefani said.

A representative for Stefani did not immediately respond to a request for comment sent outside regular business hours.
