Este Haim is filling a blank space with the perfect piece of advice.

Ahead of Taylor Swift’s upcoming nuptials to Travis Kelce, her close friend revealed what she recommends soon-to-be brides do on their special day.

“Have as much fun as possible. Just enjoy it,” Haim, who recently married entrepreneur Jonathan Levin, told People.

“I was so overwhelmed. I mean, I enjoyed my wedding so much. But I wish that I had also just stopped for a second and took it in. I didn’t get to do that,” the singer recalled.

Haim shared that those tying the knot should “just have the best time. Have so much fun.”

“All those people might not be in the same room ever again,” she expressed.

For Haim, 40, the best part of married life is having a “great time together.”

“We just love each other and have fun together. And I’m always like, ‘We better still be dating forever.’ As long as we do that — always be dating — we’ll be fine.”

Haim and Swift have been close pals for years, most recently attending a New York Knicks game together along with Haim’s sister Alana.

The trio sported custom blue tees with orange lettering to the sports outing.

Swift, 36, meanwhile, is set to wed the NFL star, also 36, on July 3 at Madison Square Garden in New York City.

“Everyone’s been sworn to secrecy,” a source shared.

Reports previously surfaced that Kelce and Swift were looking to marry in Rhode Island — where the latter owns a large estate next door to a hotel.

At the time, rumors swirled that Swift cut a hefty check for a bride-to-be who had booked out the date, June 13, at the waterfront venue the pop star wanted.

But in November, a source noted to Page Six that Swift and Kelce were thinking about scrapping that idea and going “all out” somewhere that could accommodate more guests.

The pair has remained tight-lipped about wedding details, with Swift reportedly inviting guests over the phone.

Karlie Kloss, Gigi Hadid, Sombr and Selena Gomez are set to attend, while Miles Teller and wife Keleigh Sperry have been snubbed.

Blake Lively, meanwhile, has been given an invite.

The gesture is an “olive branch” from Swift amid the two’s fractured friendship.

Ahead of their upcoming ceremony, Kelce spent Friday night partying at Chris Lake’s Los Angeles concert, even dancing on stage to a remix of his fiancée’s song.

Kelce was seen jumping up and down, screaming to the crowd, “I know y’all feel it” and “lose your f—ing minds.”

Meanwhile, on Wednesday, Swift’s Rhode Island mansion saw a flurry of activity, including a group of women clad in all black, and one woman dressed in white.

Swift’s best friend Abigail Anderson Berard was also spotted on the property.

Later in the evening, Kelce had a boys’ night out at The Birds Street Club in Los Angeles with his brother, Jason Kelce, former Kansas City Chiefs teammate Ross Travis and comedian Druski.

Travis popped the question to Swift after two years of dating in August 2025.

Despite keeping mum about their plans, a couple months after their engagement, the songwriter said that she knows her wedding will be “fun to plan.”

“I’m so excited about it,” she gushed while on the “Graham Norton Show” at the time.

“I think the only stressful weddings are the ones where you have a small amount and people are on the bubble.”
