Inside Taylor Swift and Travis Kelce's "Very Genuine" Connection

Best believe Taylor Swift and Travis Kelce had a bejeweled weekend in NYC.

In addition to stepping out for dinner dates, the Grammy winner and the Kansas City Chiefs tight end also made surprise cameos on Oct. 14's Saturday Night Live. To celebrate, the duo headed to the NBC sketch comedy show's after-party at Catch Steak, where they mingled with musical guest Ice Spice.

"Taylor did a group cheers with Ice in celebration of her SNL performance, then she sat next to her for a while at the table talking," a source tells E! News. "Taylor got up and came over to Travis and put both her hands on his shoulders and kissed him and they were standing there holding onto each other."

Throughout the event—which was also attended by SNL host Pete Davidson and his rumored girlfriend Madelyn Cline—Travis was spotted "periodically coming over to Taylor and checking back in with her" as they chatted with fellow attendees, according to the insider.

And although both Taylor, 33, and Travis, 34, have yet to publicly address their relationship status, it's safe to say they've grown close in recent months.

"Taylor and Travis seemed very comfortable together," the source shared. "He was a total gentleman to her all night: holding hands, opening car doors, making sure she is good. They both seem very happy and smitten with each other."

"It seems very genuine," the insider added of their connection. "They were both smiling all night, super friendly and talked to everyone. They weren't taking any photos inside, but they were both endless good vibes and very chill."

The "Blank Space" singer and the two-time Super Bowl champion have been spending more time together ever since Travis invited Taylor to attend a Chiefs game, which she took him up on in late September.

Since then, Taylor has attended two more games in support of the NFL player—and he couldn't be happier. As Travis explained in an Oct. 6 press conference, "It feels like I was on top of the world after the Super Bowl—and right now, even more on top of the world."
