The couple, who have been married for 12 years, were spotted dancing in the crowd at Caesars Superdome, leading a fan to record them and post it online.

Earlier in the day the 37-year-old It Ends With Us actress and 48-year-old Deadpool & Wolverine star were spotted landing in Louisiana with their brood.

The pair share daughters James, nine, Inez, eight, Betty, five, and son Olin, one.

Lively and Reynolds previously attended two of the 34-year-old music artist’s shows in Madrid over the summer.

Blake Lively and Ryan Reynolds attended their close friend Taylor Swift ‘s Eras Tour concert in New Orleans on Friday night

They brought their daughters one night and enjoyed a child-free date night at a second performance.

In September 2023, Blake brought along her two oldest children to Taylor’s Philadelphia tour stop.

During her performance the music sensation took a moment to acknowledge the special guests as she mouthed what appeared to be ‘Hi, James! Hi, Inez!’

Taylor’s song Betty is named after Blake and Ryan’s daughter — and before performing it is when the pop star shouted out the children’s names.

Swift and Lively have a long and close friendship that dates back to 2015.

Swift received a warm welcome in New Orleans ahead of her three-night residency, which kicked off ahead of the weekend.

The Karma hitmaker and her fandom, dubbed Swifties, stay connected through friendship bracelets.

To commemorate the ongoing theme, the New Orleans superdome has been adorned with a giant friendship bracelet reading: ‘Taylor Swift, The Eras Tour.’

Earlier this year designer Christian Louboutin shared that he made more than 250 pairs of shoes for the production of the Eras Tour.

Chatting with Vogue, the footwear architect dished, ‘When working for performers, it’s better to start with a very large number of styles that will end up in a selection of designs which seem the best for the stage.’

It was also shared that he dreamed up 60 new pairs of shoes for the pop star to take on the European leg of her successful tour.

Hundreds of strass crystals were used in the collection and Louboutin noted, ‘I’ve learned a few magic tricks to make sure the silhouette still looks great with shoes being 100% easy to perform in.’

Swift introduced a new section of her concert in early May, after releasing her The Tortured Poets Department album in April.

Along with the addition of songs came new footwear, including a custom pair of booties inspired by archival Louboutin styles.

‘Joseph Cassell and Taylor were very instrumental in communicating all the different acts and having shoes that reflect the genre she wore then with an updated modern twist,’ Louboutin shared.

Taylor revealed during her a May concert in Paris that she had been working on The Tortured Poets Department segment of the tour since 2023.

‘We started planning this surprise for you about eight or nine months ago and then when we got “two months off” of the Eras Tour, we really didn’t take any time off at all.

‘We just went directly back into rehearsals. So I’d like to give it up for my crew, my dancers, and my band,’ she said during a break in the music.

The Tortured Poets Department was released on April 19 and is Taylor’s eleventh studio album.

The singer’s tour will wrap in Vancouver on December 8.
