Blue's Duncan James "fulfilled a fantasy" as he performed in drag on Thursday night.
The former Hollyoaks star took to the stage at Proud Cabaret in London after the club was one of several venues to reopen following the end of the national lockdown.
Taking to Instagram before he performed, Duncan told fans: "Hello everybody it is me Duncan James.
"It's my opening night at Proud Embankment and I cannot wait to get on that stage fulfil my fantasy. Make sure you book your ticket now."
To Perform Sweet Transvestite from The Rocky Horror Picture Show, Duncan, 42, showed off his muscular frame in a pair of red and black fishnet stockings with a bejewelled garter belt.
The costume was completed by a plunging lace corset which showed off his tattooed chest and arms, with an oversized pearl necklace at the neck and lashings of blue eyeshadow.
Dancing On Ice alum Duncan acted as compere, while also performing six of his own songs.
His performance certainly went down well with the audience, who included Duncan's former WAG pal Lizzie Cundy.
Lizzie shared footage of a burlesque dancer to Instagram, writing: "One of the best shows ever."
The '60s and '70s inspired show features world-class jazz musicians, acrobats and fire breathers, including alumni from Cirque du Soleil and the Moulin Rouge.
The Proud Embankment website advertised the show in advance, writing: 'Proud Embankment and Brighton proudly presents it's newest, hottest show.
'Cabaret All Stars is a Vegas style show introduced to London's West End by our favourite Boy Band heartthrob and West End star Duncan James."
Before trying his hand at cabaret, father-of-one Duncan appeared on the soap Hollyoaks as Ryan Knight from 2016 to 2018.
He has appeared in various West End shows including Chicago and was a member of the group Blue from 2000-2005.
