The 2015 BBUK contestant previously auditioned for X Factor before he appeared on Big Brother without success.
Now Simon's back for another go, and was seen on this evening's latest episode on ITV.
In this evening's episode, try outs moved to Manchester with guest judge Alesha Dixon alongside Simon Cowell, Louis Walsh and Sharon Osbourne.
It's there we met 48-year-old entertainer Simon from Beckenham.
Now hoping for success on X Factor after his Big Brother appearance, so-called Showbiz Simon performed Robbie Williams' Let Me Entertain You - with a few lyrical changes.
"Tell me, do you do panto?" asked Sharon Osbourne after the audition.
Simon got enough yeses to make bootcamp, and will be see again next weekend.

Other acts on tonight's final episode of auditions included duo Boybanned, made up of Scott (28 – student nurse) and Ben (27 – joiner) who up until the morning of the audition used to be a trio, before third member Jack decided not to audition.
Another duo taking part this evening was Just Us, made up of retired friends Anna-Maria (67) and Carol (70), who wanted to prove "whatever your age, you can still make your dreams come true".
Also at the auditions as a pair - but auditioning separately - were best pals from Blackpool Johnny Wright and Jenny Ball. However there was heartbreak for Johnny who got a no from the judges as Jenny made bootcamp.
As auditions wrapped up we also met Berget Lewis, a 45-year-old singer from Amsterdam, Netherlands who was hoping for a bigger career in the UK after enjoying some success in her home country.
The X Factor 2017 continues Saturday and Sunday nights on ITV.
