The group will make their debut at the event today as they sign off a great 2013.
The Vamps are set to make their debut at the Jingle Bell Ball today (8th December) and have told Capital they are "nervous" but have woken up ready to go.
James and Bradley said they came down to watch the first night as Katy Perry, Union J and Tinie Tempah all performed.
"I've never even been to the O2 Arena before," confessed James.
After talking about any jitters they had, he added: "Today we've woken up ready."
Bradley simply put it: "I can't wait."
Today's final night of the Ball will feature sets from the likes of Lady Gaga, Jason Derulo, Lawson and Jessie J.
