The 24-year-old 'Lego House' star and the 25-year-old 'I Knew You Were Trouble' singer will be hosting the party after the awards tomorrow night (17.05.15), and have hired out the £22,000-a-night Nobu Villa in the Caesar's Palace hotel, which Ed may have chosen for its ginger-scented rooms.
According to The Sun, the 10,500ft venue has its own bar, sauna and rooftop garden with whirlpool tub, and is expected to play host to the likes of Hozier, Lorde and Taylor's boyfriend Calvin Harris at the weekend.
The 'Blank Space' star must be throwing the party to thank the people around her, as she recently said she feels "really lucky" to have so many fantastic famous friends.
As well as Ed, Taylor has a group of close pals that includes Selena Gomez, Karlie Kloss and Lena Dunham who she can rely on at any time for support and she says it's great that they all understand the pressures of fame.
She previously said: "I can say I'm really lucky to have friends like Karlie, Lena and Selena that I can call at any time day or night and who understand how my life feels."
The pop superstar and her famous friends regularly get together and they often enjoy "themed-nights".
She said: "Sometimes we organise themed nights. We all agree to make nice Shirley Temple cocktails, go to the new Ralph Lauren restaurant (to shop)."
