But before she and One Direction's Harry Styles annoyed off the rest of his mates by taking her private plane to London and leaving them to fly—egad!—commercial, the pair enjoyed the sidelines at Z100's Jingle Ball in New York while not onstage performing themselves.
And, it turns out that a resourceful amateur videographer managed to capture some footage of the cute couple boppin' along to B.o.B's "So Good." We can see Taylor, clad in a super-festive glittery top, excuse herself for a moment—and plant a big kiss on Harry before walking away.
Afterward, you can see Harry throwing his arms playfully around an older gent he knows and continuing to enjoy the music. (Alas, there's no way to say for sure if he was blushing.)
In the meantime, there were no lasting hard feelings between Taylor and One Direction. After their show Saturday night at London's O2 arena, she joined them on their tour bus for a three-and-a-half-hour ride to Manchester, where they performed Sunday night on the finale of The X Factor U.K.
And the honeymoon phase continues: Taylor and Harry were at a restaurant today in Derbyshire, in the English countryside, having dinner with two other people. An eyewitness tells E! News that the pair were "the nicest people ever," and "just seemed normal...like they were a couple, but not all over each other, obviously."
Apparently, they had dining on their minds.
"They were meeting friends to get something to eat," a source told E! News. "They came in for dinner last night and stayed for a couple of hours."
The obliging pair also posed for pictures with an adoring fan, who tweeted that she was the "happiest person alive!!!" after meeting Harry and Taylor.
