Taylor Swift and Travis Kelce got the rare opportunity to experience a low-key outing, as Page Six has learned that the couple was barely bothered while enjoying their Mother’s Day brunch.

An eyewitness tells us the pop superstar and the Kansas City Chiefs tight end, both 35, went almost undetected at Talula’s Garden in Philadelphia, where they celebrated his mom, Donna Kelce, 72, on Sunday.

We’re told Travis’ brother, Jason Kelce, Jason’s wife, Kylie Kelce, and at least some of their daughters were also in attendance.

According to our insider, the group was not seated in a private room but rather among the many patrons who were dining at the packed restaurant.

Our source dishes that one young girl noticed Swift and pulled out her phone but seemingly decided not to snap a photo.

In fact, the only two pictures of the outing that appear to exist were taken by a sneaky onlooker who posted them on TikTok.

Our informant goes on to gush over Jason and Kelce’s girls, saying they were extremely polite, sweet and adorable.

Jason, 37, and Kylie, 33, are parents to Wyatt, 5, Elliotte, 4, Bennett, 2, and Finnley, almost 6 weeks.

Kylie follows Talula’s Garden on Instagram, so it’s possible she and her husband — a retired Philadelphia Eagles player — frequent the establishment.

For the low-key afternoon, Swift wore a black Christy Dawn dress featuring a daisy print that fans felt was a telling nod to one of her lyrics from the 2017 album “Reputation” — notably, one of the two she has yet to rerecord.

Sunday’s brunch marked her first public sighting with Travis in months; however, a source assured Page Six in late April that the two are “still so in love.”
