Fat Tuesday brings out the wild side - even in celebrities. Over the years, big names have hit the streets of New Orleans to celebrate Mardi Gras with beads, parades, and full-on party mode.

From singers to athletes, these stars stole the show:

Shaquille O’Neal Rules as King

Shaq didn’t just show up for Fat Tuesday. He wore the crown! The basketball great rolled through the Krewe of Bacchus parade as the Celebrity Monarch. Dressed in royal gear, complete with a golden crown, the NBA legend waved to crowds and tossed beads like a pro.

Fans cheered as he embraced the Mardi Gras spirit with full energy. Shaq didn’t hold back. He danced, posed, and even threw some signature Shaq-style humor into the mix.

Katy Perry Beads Up

Singer Katy Perry knows how to make an entrance. At the Endymion Mardi Gras Extravaganza, she hit the stage in a dress made entirely of colorful beads. That same night, New Orleans declared March 1 as Katy Perry Day.

Fat Tuesday got a pop-star-level glow-up with her there. She belted out hits, smiled big, and partied like a local.

Nicole Richie Gets Wild

Nicole Richie joined the Mardi Gras madness in 2025 and fully leaned in. She took a trip with friends, shared behind-the-scenes moments, and got into the festive chaos. She joked on Instagram about losing her glasses but finding beads, crawfish, and a few bruises.

Nicole / IG / Richie was not trying to stay polished at all. The “Chuk” star embraced the mess and fun that comes with Fat Tuesday.

Her photos showed a carefree, party-loving side that fans loved.

Livvy Dunne Shines in Green

LSU gymnast Livvy Dunne led the Krewe of Endymion parade as Grand Marshal this year. She showed up dressed in head-to-toe green and smiled wide from her float.

It was a big moment for the rising star, and she soaked up every second.

Harry Connick Jr. Returns Home

Just weeks after his father passed away, Harry Connick Jr. made a quiet but strong return to Mardi Gras in 2024. At the Krewe of Orpheus parade, he surrounded himself with his hometown crowd and let the music and tradition carry him.

There was no big speech. Just presence. People saw him soaking in the moment.

Kevin Dillon Goes All Gold

During the 2024 Krewe of Bacchus parade, Kevin Dillon—best known for “Entourage” - showed up as King. Wearing gold and blue, he stood out as he tossed beads into the crowd with a huge grin.

Fans loved it. He brought the bold, flashy energy Mardi Gras thrives on.

Darren Criss Keeps It Classic

Darren Criss knows New Orleans. He married his wife Mia Swier there in 2019, so it’s no surprise he returned to ride in the 2023 Krewe of Orpheus parade. He flashed beads, waved nonstop, and stayed high-energy the whole time.

He fit in like a local. For Fat Tuesday, Darren brought charm, music, and joy.
