The 27-year-old was replaced by N-Dubz star Tulisa Contostavlos, 22, when she decided to quit the show to star on the new US series, but was later sacked from it.
According to UK newspaper Daily Mirror, fans of the star in the audience were chanting 'bring back Cheryl, bring back Cheryl' before the judges made their appearance to assess the latest contestants.
It's claimed Tulisa had a hard time from the fans when she told one contestant she didn't connect with the audience.
But she later proved popular with them when she told one 'cocky' singer that they had a bad attitude.
