Taylor and Travis Kelce took a cross-country hop to spend Easter Sunday with Jason and Kylie and their family at their home in Pennsylvania.

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

Kelce, also 34, and his Pennsylvania-born pop princess jetted in from Los Angeles Sunday morning for the flying visit to Jason’s home in the upscale enclave of Haverford Township just nine miles outside Philadelphia city center.

Kelce and Swift no doubt took part 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 in which she could be seen scrambling around her parents’ yard, fighting with younger brother Austin, 23, in a fierce bid to find more Easter eggs than him.

She posted it with the captioned: ‘When your parents arrange a competitive sibling Easter egg hunt failing to take into account that their children are Ross and Monica,’ a reference to the characters on Friends.

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

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

They flew back to the west coast Monday morning landing at Burbank airport and deplaning amid a thicket of umbrellas around 1:30pm local time.

The couple has been all but inseparable since Swift returned to the States having completed the Australia and Asia legs of her monster Eras Tour last month and recently came back from a sun-filled vacation on the Bahamian island of Eleuthera.
