The Sugababes won't change their line-up again in 2011.

The girl group underwent another change of personnel in 2009 when founding member Keisha Buchanan was replaced by Jade Ewen, but the singer insists the current trio - Jade, Amelle Berrabah and Heidi Range - won't be altered.

Jade said: "The girls must be pretty tired now because it's the fourth line-up change. Our management joked with us if this doesn't work we'll have to call it quits."

The Sugababes were originally made up of Keisha, Mutya Buena and Siobhan Donaghy when they launched their music career in 2000.

Siobhan was replaced in 2001 by Heidi, and then Amelle took Mutya's place in 2005.

Just as the girls are looking forward to a stable and successful 2011, Heidi can't wait for her wedding in the New Year.

The 27-year-old blonde is set to tie the knot with TV presenter Dave Berry and has been busy making plans for the big day.

She said: "We've been looking at venues and I think I've found my dress but I'm not giving away any details. I don't Dave to know what it's like."

Dave proposed to Heidi on New Year's Eve 2009 while they were enjoying a holiday in the Caribbean.

It is believed the pair will tie the knot in the early part of 2010.
