Grammys After-Party Drama! Taylor Swift, Adele & More — Who Was Caught Together & Who Ditched Celeb Pals For A Burger

The Universal Music Group's 2016 Grammys after-party has the biggest turn out! A-listers Taylor Swift, Zendaya, Joe Jonas, Anna Kendrick, Brooklyn Beckham, and Bella Hadid — who arrived alongside boyfriend The Weeknd after their red carpet debut together — all make sure to make an appearance.

He's definitely 89 years young! Jazz legend Tony Bennett sure knows how to throw a party as he welcomed an army of new generation youngsters to his Republic’s affair. Attendees included Ariana Grande, Big Bang Theory’s Kaley Cuoco, Shawn Mendes and James Bay, to name a famous few.

Later that evening, Calvin Harris — who had some serious making up to do — finally made it to his girlfriend's side. The famous couple was accompanied by Taylor’s date for the night, Selena Gomez, and close friends Lorde, and Ellie Goulding.

First-time Grammy winner Meghan Trainor posed with singer-turned-first-time-daddy, One Direction boy bander Louis Tomlinson at the Sony Music after party in Bel Air, and was later seen with Justin Bieber at The Nice Guy.

After suffering through a serious technical faux pas during her award ceremony performance, "Hello" singer Adele decided to skip the conventional after-party route — she announced on Twitter that she decided to treat herself to n In-N-Out of burger instead!
