Taylor Swift and Travis Kelce traveled across the country to spend Easter Sunday with Jason, Kylie, and their family in Pennsylvania.

Swift also made another step into the heart of the Kelce clan, as DailyMail.com can exclusively reveal that Kelce’s lovely nieces, Bennie, 1, Elliotte, 3, and Wyatt, 4, were introduced to their Auntie Tay for the first time.

Kelce, 34, and his Pennsylvania-born pop princess arrived from Los Angeles on Sunday morning for a flying visit to Jason’s house in Haverford Township, an upmarket enclave only nine miles outside Philadelphia.

Exclusive photographs obtained by DailyMail.com show their car parked in the driveway of Jason’s quaint stone home, which has a wraparound deck and is set on an acre of landscaped gardens, with a huge patio and swimming pool.

Taylor Swift and Travis Kelce traveled cross-country to spend Easter Sunday with their brother Jason, his wife Kylie, and their family at their home in Pennsylvania.

The couple delighted their legion of fans with charming Easter posts on their official fan sites on Sunday, with the NFL tight end sharing a shot of himself with bunny ears.

The couple’s Cadillac Escalade was seen parked outside Jason’s Pennsylvania farm, where they spent Easter Sunday with his family.

Travis and Taylor left Pennsylvania on Monday, and the singer’s private jet was seen landing at Burbank Airport.

His superstar girlfriend was more cautious about being photographed on the tarmac, covering up with umbrellas as she deplaned, before getting into a car.

Kelce and Swift almost certainly participated in the family’s annual Easter egg hunt, something Swift has always enjoyed.

Swift, then 25, shared a 29-second video on Instagram in 2015 showing her racing around her parents’ yard, fighting with younger brother Austin, 23, in a desperate quest to discover more Easter eggs than him.

She captioned it, ‘When your parents prepare a competitive sibling Easter egg hunt failing to take into account that their children are Ross and Monica,’ referring to the Friends characters.

Kelce and Swift are thought to have stayed at the Four Seasons after spending the day with Jason and his family.

Swift has previously stayed at The Ritz-Carlton and dined at Four Seasons’ Jean-Georges restaurant.

They returned to the west coast on Monday morning, landing at Burbank Airport and disembarking under a thicket of umbrellas around 1:30pm local time.

The couple has been almost inseparable since Swift returned to the United States after finishing the Australia and Asia legs of her mammoth Eras Tour last month. She recently returned from a sun-filled vacation on the Bahamian island of Eleuthera.
