Pink calls the song "a song she regrets recording" and considers it "a real mistake"

Not all of Pink's songs are "F*ckin' Perfect" in her eyes. During her summer carnival tour, the three-time Grammy winner looked back at some of the biggest hits and biggest flops of her 23-year solo career, admitting there's one song she should never have recorded. The single dates back to the 2009 SpongeBob SquarePants special "Truth or Square ," which featured guest appearances by Pink and several other celebrities.

"I did put out the Spongebob stuff. 'We Got Scurvy'?" Pink told the Los Angeles Times about her worst single. "I wish I'd never done this."

The made-for-TV movie is a two-part sixth season celebrating SpongeBob SquarePants' 10th anniversary. It switches back and forth between live-action scenes and animation, featuring a celebrity-studded telethon of Patch the Pirate, in which Pink plays the pirate singing "We Got Scurvy." The lyrics included lines like: "Our gums are black and our teeth are falling out" and "A pirate ain't worth it, unless he got scurvy." Looking back, Pink calls the song "a real mistake." .

Mistakes or not, Pink is in good company in this episode. "SpongeBob SquarePants: Truth or Square" also stars Robin Williams, Tina Fey, LeBron James, Will Ferrell, Rosario Dawson, Eddie Deason, Craig Ferguson, CeeLo Green and Ricky Gervais. Additionally, her song was featured on Spongebob's 2009 Hottest Album.

Another song Pink now regrets is "True Love," her 2013 collaboration with Lily Allen that was inspired by her relationship with husband Carey Hart. She listed "True Love" as a contender for one of her worst singles before remembering she'd recorded "We've Got Scurvy." "It's despicable," she told The Times . "Kyrie is thick-skinned, but I owe him a love song."

While Pink may feel like she's made some mistakes in her career, she knows she has a lot to be proud of. She suggested "So What" and "Get the Party Started" as two of her best singles and acknowledged her hard work. "I've been fighting on the sidewalk for 25 years because that's where I belong," she told The Times in an interview. "Or I should say, that's the stadium where I belong."

Pink has been celebrating her wins on the road this summer and fall. In August, after a record-breaking show in Milwaukee, Wisconsin, she posted on Instagram, "I was just told that I was the first woman to headline a stadium in Wisconsin and that we broke the crowd record Record. I don't know why they look at me when they tell me these things. I'm like, 'Are you sure?' ... I have so much love for all of you."
