Taylor Swift Dines with Sophie Turner, Blake Lively and Brittany Mahomes in NYC

Taylor Swift's gearing up to root on Travis Kelce for the second week in a row, but not before grabbing dinner with some famous gal pals ... stepping out with Sophie Turner, Brittany Mahomes, and Blake Lively.

Taylor and crew hit Italian hotspot Emilio's Ballato in NYC Saturday night -- arriving with Blake and later joined by Sophie and Mahomes ... who she recently got acquainted with last weekend following Kansas City's win at home.

Of course, Taylor's been spending a lot of time with Sophie as of late, noticeably taking her side in a battle with Joe Jonas as they fight for custody and issues surrounding their divorce.

Blake's a longtime friend of Taylor, but Mahomes is certainly a new addition to the girl squad.

TMZ broke the story ... Taylor and Brittany hit it off at Travis Kelce's afterparty in KC last weekend, chatting a bunch and at one time taking a shot together. We were also first to obtain a photo of Taylor and Travis looking rather comfortable at the bash ... as she wrapped her arms around the NFL superstar.

Travis and his Kansas City Chiefs are set to take on The New York Jets Sunday night, and sources tell us Taylor will be in attendance.
