Selena Gomez Gets Emotional Again at Taylor Swift’s Birthday Party

At Taylor Swift's birthday bash at her Tribeca apartment on Friday December 13, Selena Gomez was overflowing with emotions about her on-an-off beau Justin Bieber.

The star-studed birthday event was filled with celebrities like Beyonce, Jay-Z, Justin Timberlake who enjoyed beers, pizza and sushi. Gomez, on the other hand, was reportedly being emotional with the "Baby" singer.

According to an insider, "The Heart Wants What it Wants" singer shouted, "No one understands me! My boyfriend doesn't even understand me," and bystanders - including guest Sam Smith - just stared at her via a report by US.

At last month's American Music Awards, Gomez became emotional onstage while singing her newest hit "The Heart Wants What it Wants." At the end of her performance, she was seen looking at BFF Swift, all the while reassuring Gomez that Swift understands.

But the party never stops, even with Gomez melodramatic scenes happening on the upper terrace. The party pushes on and everybody had a total blast.

The party was completed with a karaoke machine and kicks off after "Blank Space" singer and the birthday girl's performance at the Z100's Jingle Ball. The notable guest list also includes, Swift's BFF Karlie Kloss, Kelly Osbourne, 5 Seconds of Summer, HAIM, Nick Jonas and Olivia Culpo, Charli XCX, Chrissy Teigen, Shawn Mendes, Ansel Elgort, and Jaime King.

The A-list crew posed for a snap with the birthday girl, who captioned the pic: "So this is being 25.... #WHAT #bestbirthdayEVER."
