Swift and her pals first attended a Republic Records party at the swanky West Hollywood restaurant Ysabel, which featured an A-list guest list of attendees including Selena Gomez, Nick Jonas and Ariana Grande.

The generous "We Are Never Ever Getting Back Together" singer paid the huge tab for her pals' hair, makeup, stylists and transportation, our eyewitness said.

Gomez had a boozy evening -- "She started to get pretty f***ed up," our eyewitness said -- downing four vodka sodas at Ysabel, where she "was flirting big time with Nick Jonas."

RadarOnline.com's eyewitness said that Grande and her brother Frankie could not get close to Swift, who "made it clear to security not to let them near."

"At first, I thought it was just Frankie, but it was crystal clear Swift wanted nothing to do with either of them," our eyewitness said, noting that Grande "gave up" trying to approach "after a few minutes."

Empire beauty Serayah McNeil tested Swift's patience as she spent too much time taking selfies and Snapchats at the affair, leading Swift to ask her to put the phone away. It "was fine at first," our source said, but eventually Swift got "super-annoyed" with her pal's hijinks.

At a get-together at Swift's house afterwards, according to our eyewitness, everyone changed into sweats and Swift Facetimed her beau Calvin Harris for a romantic exchange with many "I love you's" going both ways.

The kickback was well-catered with sushi, vodka and fireball shots, which Swift's inner circle all indulged in, according to our eyewitness. Swift sipped on Ketel One.

Gomez said, according to our eyewitness, "I can't believe we used to be friends ... I should've reached out that night she cut her hair and posted the pic on Twitter."
