“She’s the biggest star in the world and it’s no secret dating an athlete is very tough, but they’ve been texting and talking on the phone between the pockets of time they get to spend with each other,” the source shared.

Swift and Kelce have stepped out for a handful of dates; in mid-October, they had dinner at Nobu and the Waverly Inn in N.Y.C., and popped up at the season premiere of SNL with his-and-hers cameos, then headed to the afterparty. And she’s been spotted cheering him on at four Kansas City Chiefs games so far, then meeting him after the game to walk through the stadium hand-in-hand. Most recently, she was seen planting a giant smooch on him after he attended her show in Buenos Aires, Argentina.

Here, every photo so far of the happy couple together.

In their first real show of PDA, Taylor Swift was pictured planting a big smooch on Kelce’s cheek after the Kansas City Chiefs defeated the Los Angeles Chargers on Oct. 22. The photo was snapped as the two were hanging out with Kelce’s teammate Mecole Hardman Jr. and his girlfriend Chariah Gordon after the game.

The Grammy winner and NFL star were later spotted holding hands as they left Arrowhead Stadium.

The new couple matched in Chiefs red, with the pop star showing her team spirit in a vintage 1990 USA Kansas City Chiefs sweatshirt from Ellie Mae Vintage, while the Chiefs tight end wore a checked red shirt.

On the night of Oct. 14, Swift and Kelce walked hand-in-hand into Nobu in Midtown Manhattan.

In a video clip from the restaurant that circulated on social media, Kelce, 34, could be seen keeping his hand raised as he guided Swift, 33, down a flight of stairs, before pointing a single finger in the air in celebration.

After the pair made it down the stairs successfully, Swift took a moment to greet people at the bottom.

Following dinner, the stars headed to SNL, with Kelce scoring a line in a sketch about the NFL’s interest in the couple’s relationship and Swift introducing the musical guest, her friend and collaborator Ice Spice.

“Taylor and Travis are both big Pete and Ice Spice fans, so they came last minute to show their support,” a source told PEOPLE. “It was a surprise to the audience and the staff, no one knew they were there.”

The next stop was the afterparty at Catch Steak, where “they were so talkative,” another source told PEOPLE. “They were really fun. They talked to every single person in the room that talked to them.”

“They were super cool. Super nice, super happy,” the insider added, noting that Swift and Kelce stayed at the party “until after 4 a.m.”

On Oct. 15, the pair grabbed a late-night dinner at the Waverly Inn in the West Village, after Kelce spent the day watching his brother Jason and the Philadelphia Eagles take on the New York Jets in New Jersey.

“Taylor’s unlike anyone Travis has dated before,” a source told PEOPLE of the pair. “It was very unexpected for his friends, but he’s so into her and very, very happy.”

Fans on social media fixated on the pair’s body language throughout the weekend, with many highlighting Kelce’s gentlemanly move of opening Swift’s car door when they arrived at the SNL afterparty, taking over for her security guard.

Following a dinner out in Buenos Aires, Argentina, Kelce was seen in the stadium dancing along to Swift’s music (and reacting with glee to a lyrics change that referenced him) — then waiting for the singer after the show, at which point he was greeted with a running hug and kiss.
