Kelsea Ballerini and Chase Stokes stun as Sandy and Danny from Grease at Heidi Klum's Halloween party

Kelsea Ballerini channeled Olivia Newton-John’s iconic Grease character Sandy in a show-stopping look for Heidi Klum’s Halloween party.

The 31-year-old country star captured the classic ‘50s vibe, paying tribute to the late Australian icon’s role as Sandy Olsson, the sweet, shy girlfriend of John Travolta's Danny Zuko in the 1978 musical classic.

Dressed in a skintight black halter top and leather leggings, the Miss Me More hitmaker completed her look with voluminous blonde curls and bright red lipstick.

She was joined by her real-life boyfriend, Chase Stokes, who embraced Travolta's role with a slick ‘50s pompadour and a black leather Thunderbirds jacket.

The Outer Banks star couldn’t keep his eyes off Kelsea as they cozied up throughout the star-studded soirée.

Heidi’s renowned Halloween bash attracted a star-studded lineup, including Nicole Scherzinger, Valentina Sampaio, and Mario Cantone, all showcasing their most creative spooky season ensembles. 

Just a few days ago, Kelsea gushed about how much she appreciates Chase' pride in their relationship. 

The singer reminisced about how the actor made their romance Instagram official back in January 2023 — before they had even discussed whether they were 'together.'

Speaking to Entertainment Tonight during a game of Sip or Spill, she said, 'I think it is very underrated for a man to be really proud of his relationship.'

She added, '[He posted that photo] before we even had the conversation of like, "Are we together?" Even as a very independently wired woman, I love when he’s like, "This is us. Here we are." He full-sent that.'

The photo, shared on January 13, 2023, was captioned 'Lil recap' and featured the couple cuddled up at a football game, with Kelsea tagged in the post, though their faces were not visible. 

They officially stepped out together on the CMT Music Awards red carpet in April 2023.

Meanwhile, Chase recently praised Kelsea as a 'great person,' stating on Today, 'I truthfully think when you find somebody who's not just somebody you love and adore, but is also your best friend, you've kind of got the best of both worlds. 

'And she's not just a great person, but everything that you see—whether it be on social media or when she's on stage—is exactly the person she is when she's not doing those things.'

The couple is dedicated to nurturing their relationship, even when work keeps them apart for extended periods. 

Chase told People magazine, 'We don't BS each other. If we need to make the effort to show up when one’s across the country, we do.'

He believes that the same dedication they apply to their careers should be mirrored in their personal lives, acknowledging that building a fulfilling life requires hard work and isn’t always easy.
