Jessica Simpson’s American Idol comeback didn’t just rattle fans—it rattled her own body.

The 44-year-old pop star revealed she had a bizarre physical reaction just moments before taking the stage for her first live TV performance in 15 years, confessing that her feet started sweating uncontrollably—something that never happens to her.

‘Oh, my God, I was dying,’ she told Extra. ‘I can’t even tell you how long it’s been since I’ve been that nervous. I had to put hairspray on my feet to stand still. Not that it actually keeps me put, but my feet were sweating. I’m like—my feet don’t sweat!’

Unfortunately, the nerves didn’t stay behind the scenes. 

Viewers slammed her performance—especially her duet of These Boots Are Made for Walkin’ with former contestant Josh King—as ‘cringe-worthy,’ with many blasting her vocals all over social media. 

‘Jessica Simpson was an absolute train wreck on American Idol tonight!!” one X user declared. 

Another said: ‘Now Jessica Simpson is struggling and fighting for her life singing her biggest hit ‘these boots were made for walking.’

‘The epitome of cringe,’ a third marveled. 

While Jessica did her best to promote tracks from her Nashville Canyon, Part 1 EP, her shaky performance and sweaty confession may have upstaged the music.

Others insisted she ‘would never ever get a ticket to Hollywood had she auditioned’ for American Idol’s current judges, Luke Bryan, Carrie Underwood, Lionel Richie. 

‘I honestly don’t understand how she’s considered a professional vocalist?’ another hater commented.  

Despite the fierce backlash, many fans defended Simpson as they pointed out they didn’t ‘hear any glaring errors’ and she’s about on par with ‘the typical pop star vocalists [like] Katy Perry, Britney, Sabrina Carpenter, and several others.’

‘She never will be a Mariah [Carey] or Whitney [Houston], but I doubt vast majority of her detractors (here and elsewhere )could do a better job,’ one wrote on YouTube. 

On March 21, Simpson released her EP Nashville Canyon Part 1. 

Jessica dropped her last album 15 years ago – her Christmas album called Happy Christmas, which was released on November 22, 2010.

Her other albums include: Sweet Kisses (1999), Irresistible (2001), In This Skin (2003), ReJoyce: The Christmas Album (2004), A Public Affair (2006) and Do You Know (2008).

Her return to music comes after her split from Eric Johnson. 

‘Eric and I have been living separately navigating a painful situation in our marriage. Our children come first, and we are focusing on what is best for them. We are grateful for all of the love and support that has been coming our way, and appreciate privacy right now as we work through this as a family,’ she said to the outlet.

Jessica hinted at their split for months – and Eric was spotted in November 2024 without his ring.

‘Interviews in my Nashville music room where I unearthed my singular magic. This comeback is personal. It’s an apology to myself for putting up with everything that I did not deserve,’ she wrote as a caption on her Instagram post along with a snap of her in a recording studio.

Eric and Jessica married in July 2014 after dating for four years; they met through a mutual friend in 2010.

They welcomed three children together: daughter Maxwell Drew, 12, son Ace Knute, 11, and daughter Birdie Mae, five.
