Adele is keeping The Vamps awake all night.
James McVey has revealed the 'Hello' hitmaker's tour party kept him and his bandmates - Brad Simpson, Connor Ball and Tristan Evans - up with their "loud" celebrations.
James said: "We haven't seen her show yet but Adele was staying at the same hotel as us the other day. It was her tour party that kept me awake all night - it was loud."
However, the 'Can We Dance' hitmakers are much more selective when it comes to celebrating when they're on tour.
The 21-year-old singer added to the Daily Star newspaper: "We tend to pick the nights we party. The mini-bar is safe but in London we will have a few drinks with friends and family.
"Backstage it's all protein shakes, coffee, ginger and lemon. Nothing diva-ish apart from Haribo sweets. And we like to huddle and rub chins together before stage time."
Meanwhile, the boy band previously revealed their fans are much crazier in the UK, recalling the time one of them snuck into their hotel room.
Tristan said: "We've had fans from both countries jump in front of our van, which is quite extreme, but in England a fan actually got into our hotel room. That was pretty weird as Connor and James were naked at the time!"
