Okay, now things are REALLY heating up!
The little hot threesome met up at a mutual friend's birthday party at the Crosby Hotel in NYC Thursday night where friends say that Taylor was "all over" her shaggy-haired beau, even making out with him in front of all the other guests at the party! Giiiirrrrllll……
Then, after following Harry around like a "puppy dog," she introduced him to Emma, who she's always said is "like a sister" to her.
And, with Emma being the smart, talented and down-to-earth beauty that she is, we're hoping that she gave our little blonde Taylor the best advice a bestie could give.
