Taylor Swift and Travis Kelce celebrated Easter Sunday with Jason and Kylie at their million dollar Pennsylvania home before jetting back to LA on singer’s private jet

Taylor Swift and Travis Kelce went cross-country skiing to spend Easter Sunday with Jason and Kylie and their family at their Pennsylvania home.

And Swift took another step into the Kelce clan’s heart as, as DailyMail.com can exclusively reveal, Kelce’s adorable nieces, Bennie, 1, Elliotte, 3, and Wyatt, 4, were introduced to their Aunt Tay for the first time .

Kelce, also 34, and his Pennsylvania-born pop princess arrived from Los Angeles on Sunday morning for a quick visit to Jason’s home in the upscale enclave of Haverford Township, just ten miles outside of downtown Philadelphia.

Exclusive images obtained by DailyMail.com show their car parked in the driveway of Jason’s charming stone house with a wraparound terrace and set in an acre of landscaped gardens, complete with large patio and swimming pool.

The couple delighted their legion of fans with adorable Easter posts on their official fan pages on Sunday, with the NFL tight end sharing a photo of himself wearing bunny ears.

His superstar girlfriend was more careful when she was caught on the tarmac, covering her umbrellas as she stepped off the plane before getting into a car.

Kelce and Swift no doubt participated in the family’s annual Easter egg hunt — an Easter tradition that Swift has always enthusiastically embraced.

In 2015, then 25, Swift posted a 29-second video to her Instagram account of her clambering through her parents’ garden, fighting with younger brother Austin, 23, in a fierce attempt to find more Easter eggs than him.

She posted it with the caption: “When your parents arrange a competitive Easter egg hunt and don’t take into account that their kids are Ross and Monica,” a reference to the characters in Friends.

Kelce and Swift reportedly stayed at the Four Seasons after enjoying the day with Jason and his family.

On previous visits, Swift stayed at The Ritz Carlton and was seen dining at the Four Season’s Jean-Georges restaurant.

They flew back to the West Coast Monday morning, landing at Burbank airport and taking off around 1:30 p.m. local time amid a thicket of umbrellas.

The pair have been virtually inseparable since Swift returned to the United States after completing the Australia and Asia legs of her monstrous Eras Tour last month and recently returned from a sun-soaked vacation on the Bahamian island of Eleuthera.

Photos showed the couple feeling completely comfortable and enjoying time together at the beach.

In one photo, Kelce was sunbathing, with one hand lovingly resting on Swift’s bikini-clad behind. In others, they enjoyed cocktails in the surf.

Swift’s next concert date isn’t until May 9 in Paris, and Kelce is expected to join his girlfriend on at least some of her European tour dates.

Meanwhile, the Kansas City Chiefs tight end is currently enjoying some well-deserved downtime following the team’s Super Bowl victory in Las Vegas in February.

Organized team activities won’t resume until offseason workouts begin in late May.

Kelce and Swift delighted their legion of fans on Sunday with adorable Easter posts on their official fan pages.

Kelce’s showed the grinning footballer wearing a bunny-eared hat beneath the simple message “Happy Easter.”

He might have learned the lesson that simple is best after recently having to delete a 2010 Easter post in which Kelce, then an unknown player for the University of Cincinnati, wrote, “Happy Easter to everyone!!! #shoutout to Jesus for taking one for the team…haha.”

Meanwhile, on Swift’s official fan page @taylornation, her management showed adorable images of the singer, aged one, held in her mother and Andrea’s arms while wearing a pink and white fluffy bunny onesie, complete with bunny ears. The silent clip shows a timestamp of March 14, 1990.

Swift’s management team, known as Taylor Nation, referenced her love of dropping Easter eggs when they shared this clip on Instagram

The message reads: ‘Dropping Easter eggs since March 1989. What’s your favorite era?’

The throwback video was likely filmed at Swift’s childhood home in West Reading, Pennsylvania — itself a possible “Easter egg” reference to the state in which she spent Easter this year.

Swift’s habit of “dropping Easter eggs” is a reference to the hidden clues, hints and teasers the singer-songwriter is known for.

They often nod to the release date or title of new songs or give clues as to who a song might be about. She also often mentions her lucky number 13 or the year of her birth, 1989.

Her penchant for such “Easter eggs” has clearly rubbed off on her boyfriend, as eagle-eyed fans noticed that when Kelce was spotted golfing with friends (notably former NBA star Chandler Parsons) last week, his Sherwood Country Club On the baseball cap featured not only the year 1989, but also the embroidered figure of an archer.

According to online sleuths, the year was a clear nod to Swift and the archer was a reference to Kelce’s signature move: mimicking an arrow into the crowd as he runs onto the field at the Chief’s home stadium in Arrowhead, Kansas City.

Fans have also pointed out that Swift performs the same move while performing “The Archer” during her Eras tour.
