It looks like John Travolta‘s daughter, Ella, was meant to follow in her famous father’s hand-jiving footsteps! As the iconic Grease actor, 65, reunited with costar Olivia Newton John for the Meet n’ Grease sing-along event, Ella was in the crowd cheering them on.

Following one of the sing-along’s three shows, John’s wife, Kelly Preston, took to Instagram and shared a video of Ella crooning along to her dad as he performed on the stage with his Olivia, 71. “My baby girl watching her dad at the Meet and Grease,” the 57-year-old beauty gushed in the caption.

The stunning 19-year-old also shared the heartwarming clip to her personal Instagram. “Absolutely one of the most wonderful and beautiful nights of my life,” she wrote. In the video, Ella can be seen beaming with joy as she attends the highly anticipated show with a friend. John’s little girl belted the words of “Summer Nights” as she panned the video across the stage before turning the camera on herself.

Fans of the Gotti stars’ family couldn’t help but marvel over the touching moment. “That’s one proud baby girl!” one fan wrote in the comments section of Kelly’s post, while another echoed, “She’s so proud of her dad… you truly can see it.” A third fan chimed in, writing, “She looks so beautiful sitting there singing along. The music brings back so many great memories!”

Besides the super sweet Instagram clip of Ella doting on her dad, fans were over the moon when John and Olivia reunited to play their beloved characters, Danny and Sandy, for the first time in over 40 years. The iconic on-screen pair channeled their 1970s flare as they stepped out at the Coral Sky Amphitheater in West Palm Beach on December 13.

“First time in costume since we made the movie! So excited!” Olivia wrote via Instagram alongside a photo of her and John in their legendary ensembles from the 1978 film. The Saturday Night Fever star also took to social media to respond to the nostalgic event, writing, “Grease is still the word!” Aww!

Prior to the fun-filled sing-along show, Olivia opened up to Closer Weekly about reprising their roles of Sandy and Danny. “We thought this would be really fun, because people love a sing-along movie, and we’ve never done this together before,” she exclusively gushed. “So we’ve invited three of the T-birds to come with us, they’re coming. We’re going to meet some fans before, ‘Meet n Grease.’ And then the movie … so it will be fun, I’m looking forward to it.”
