The Wanted and Pixie Lott are the second pair of acts confirmed to play on day one of this year's Capital FM Jingle Bell Ball in London.
The two-day bash takes place at the O2 Arena on the 3rd and 4th December.
The Wanted will be bringing their new album 'Battleground' to the Ball, while Pixie's sure to perform some of the impressive eight hit singles she's enjoyed in the last two years - and she's still not even 21 yet.
They both join Calvin Harris and Olly Murs on the 2011 line-up, who were confirmed earlier.
There are still two more names due to be announced for day one of this year's Jingle Bell Ball during the morning (29th October) on Capital FM.
In previous years, the Jingle Bell Ball has featured performances from the likes of JLS, The Saturdays, Black Eyed Peas and Tinie Tempah.
Tickets for the 2011 Jingle Bell Ball with Windows 7 go on general sale on Monday (31st October) at 8am.
But Capital FM VIPs will be given exclusive access to a ticket pre-sale, which opens on Sunday (30th October) at 10am.
