Jennifer Garner, Regina Hall and Chloë Sevigny Enjoy Karaoke Night in Nantucket

The cast of Five-Star Weekend took a break from set to put on a different kind of performance.

Filming for the upcoming Peacock series is currently underway in Nantucket, Mass., and several of the stars treated themselves to a karaoke night at a downtown bar called The Gaslight on Tuesday, Sept. 30.

In a video obtained by The Nantucket Current, Jennifer Garner, Regina Hall, Chloë Sevigny, Gemma Chan and D’Arcy Carden can be seen taking center stage to sing ABBA’s “Dancing Queen.”

The actresses joined longtime local Nantucket Ghost Walk guide Bill Jamieson, who apparently “had no idea who he was singing with,” according to the venue’s karaoke night coordinator Joe Minella.

“He just thought it was some ladies that wanted to sing with him,” Minella told the outlet. “What happened was Bill had signed up to sing ‘Dancing Queen,’ which he does often. And then another lady came up and wanted to sign up to sing ‘Dancing Queen,’ and she was like ‘we wanna go quickly, and just so you know, I’m with Jennifer Garner.’”

“I told her that they could sing ‘Dancing Queen’ if they wanted to, but Bill had already signed up for it, so they had to sing it with him,” he added. “So then they all sang it together.”

The Alias alum, 53, was cheering Jamieson on as he belted out the famous song and later took to the comments of The Nantucket Current’s Instagram post with a sweet message.

“♥️🥹 BILL FOREVER ♥️,” she wrote.

Garner is set to star in Five-Star Weekend — which is based on Elin Hilderbrand’s book by the same name — as a famed food influencer Hollis Shaw, who suffers a devastating loss that “starts to expose the cracks in [her] picture-perfect life.” 

“In an effort to overcome grief and find herself again, Hollis gets the idea to host a weekend away at her house on Nantucket with three friends from different stages in her life: her childhood, her twenties, thirties, and one surprise fifth star,” the official synopsis reads. “Set against a luxurious and coastal backdrop, they will mature in ways they could never imagine as boundaries are pushed and secrets are exposed.”

On Wednesday, Oct. 1, Garner offered a look into her life on the East Coast island with a series of 20 photos on Instagram. The post featured several snaps of the cast hanging out, including a group photo supporting Hall at the screening of her new film, One Battle After Another.

Garner also displayed her reunion with her 13 Going on 30 costar Judy Greer, who is slated to have a recurring role in Five Star Weekend.

“There once was a Jen on Nantucket. 🐳♥️,” Garner captioned the post.
