Cheryl Cole has ditched her married name

The singer is currently working as a judge on Simon Cowell's pop star search show 'The X Factor', and has been introduced by the music mogul by her maiden name Cheryl Tweedy.

Simon joked with the crowd about her name change as Cheryl – who requested a "quickie" divorce from her England soccer player husband Ashley Cole in May - walked into the audition room at yesterday's heat in London yesterday (23.06.10).

Simon said: "Who would like to hear from Cheryl…Tweedy' It is, now, isn't it'"

An onlooker said there was a roar of applause for Cheryl as she walked in and the audience all stood up to welcome the 'Fight for This Love' singer.

Another member of the audience said: "Cheryl's face didn't give much away. Simon was sort of joshing but she didn't laugh or look annoyed."

Cheryl, 26, is now going to have laser treatment to remove her "Mrs C" tattoo she has on the back of her neck.

The pop star cited "unreasonable behaviour" as the reason behind the end of their three-and-a-half-year marriage, after numerous women claimed to have slept with Ashley during their relationship.
