Gigi Hadid was also spotted at the singer's show at Gillette Stadium on Saturday.

Ryan Reynolds and Blake Lively are all about a concert date night!

The couple were spotted together at Taylor Swift's show at Gillette Stadium in Foxborough, Massachusetts, on Saturday, enjoying Swift's set with fellow A-lister Gigi Hadid in a VIP section. The show was Swift's third consecutive night at the New England Patriots' home field, as she works her way through the North American leg of her sold-out Reputation Stadium Tour.

Lively and Reynolds sat in the section -- affectionately named Club Meredith for one of Swift's two adorable cats -- next to the pop star's parents, Andrea and Scott, a source close to the situation tells ET.

"They were so happy and excited to be there," the source says. "They danced the entire time and had so much energy it was so adorable!"

That much was clear, as fans posted pics of the pair to Twitter prior to the concert, and even shared a vid of Lively and Hadid dancing their hearts out to Swift's 1989 hit "Style" as the show continued.

Reynolds and Lively also had another very special reason for attending the show -- their 3-year-old daughter, James, made a cameo on Swift's album! Fans spotted the A-list group excitedly reacting Swift's intro to her song "Gorgeous" -- which features James' voice saying the titular word at the start of the track -- as Lively recorded the moment on her phone.

During an interview with Good Morning America in May, Reynolds dished a little bit on James' surprise appearance on Swift's album.

"I don't know about starring, but a little intro there, yeah, umm," he told host George Stephanopolous, playing coy. "That was a voice memo that ended up on a [Taylor Swift] song. It's pretty amazing."

"My daughter has a really, really terrible ego problem now after that song," he joked. "Oh, she's insufferable."
