The glossy pictures were released as the four judges kicked off filming for the auditions stage of the competition in Glasgow on Tuesday (4 June).
Sharon made a typically show-stopping return to the programme when she arrived at the venue flanked by two hunky, semi-naked men wearing kilts!
She was an original X Factor judge alongside Simon Cowell and Louis Walsh back in 2004 when the show launched, but was replaced by Cheryl Cole in 2008.
Sharon has returned to the show for its tenth series as a replacement for Tulisa, who announced last month she was leaving to focus on other projects.
She will be juggling her X Factor judging role with her American talk show The Talk, and The Sun claims she'll be mentoring her acts via Skype while she's in LA. A source said: "She is still confident she can give her acts the support they need. There are a million ways to keep in touch with people. Many of the judges aren't there every day of the week."
Sharon said she was "overwhelmed" by the response she received in Glasgow – and by being back on the ITV show after three years away.
Yesterday's auditions took place at the Grosvenor Hilton Hotel. In a twist introduced for the tenth season, hopefuls must now complete TWO auditions to progress. First they have to impress the judges in an intimate audition, then, if successful, wow them again in front of an arena crowd.
