Apple will host the next of its series of free music 'Live From London' gigs tomorrow night, featuring chart-topping act, the Sugababes.

Sugababes currently hold second place on the iTunes UK Music Store with their recently-released "Ugly" single. The band is hotly-tipped to take the coveted number one Christmas album slot.

Sugababes - Keisha Buchanan, Mutya Buena and Heidi Range - formed in 1998. They have already had four UK number one singles and two UK top five albums as well as number one album "Taller in More Ways" in 2005.

The act will perform 9pm at the store. Space is strictly-limited and will be allocated on a first-come, first-served basis.

The Genius Bar will offer restricted service from 7pm.
