The stars came to Manchester this week to help raise money for Children In Need.
Lady Gaga stole the show as she arrived on stage in a high-cut leotard and fishnet tights, treating the audience to two raunchy performances during the evening; "Born This Way" and her new single, "Marry The Night".
X Factor judge Kelly Rowland also worked a sexy look on stage in cut-off denim shorts, fishnets and a red leather jacket while Tulisa, who performed with The Collective, a supergroup comprised of some of the UK's top urban acts, kept it classic and low-key in a black waistcoat and sparkle detailed leggings.
Jessie J worked her trademark statement style in a green leopard print style dress by Katie Eary as she performed a duet with James Morrison.
Other performers on the night included Gary Barlow, JLS, Coldplay and Michael Buble.
