Louise Redknapp has treated her 707,000 Instagram followers to a sizzling Throwback Thursday photo on her story.  The 45-year-old took to her Instagram story with a look back at her time in the musical Cabaret, in which she played Sally Bowles.  The mum-of-two posed alongside Pop Idol champ Will Young, with the duo stripping down to their underwear for a fun snap.  Louise wore a baggy khaki green top, while her lower half was another story.  She stripped to a set of black stockings and suspenders, with the sheer tights teasing more of her slender toned legs than what was visible.  Meanwhile, former Strictly Come Dancing star Will Young wore a fluffy wool jumper and practically nothing down below.  He could be seen in a pair of black underpants, while there was a hint of a pair of statement boots visible too.  Louise pouted as she lifted one leg up and hung off Will’s shoulder, while he placed one hand on his hip in a powerful stance and wrapped his arm around his friend and co-star.  Former Eternal singer Louise was all dolled up with bronzed skin and smokey shadows around her eyes, while her caramel blonde locks were pulled away from her face in a messy ponytail.  Will’s face was painted with a thick layer of white paint, while his cheeks were given a dusting of bright pink blusher and his lips were a similar coral hue.  His short hair was flat to his head, while a painted-on hairline gave him a very square-looking face.  Louise and Will appeared in Rufus Norris’ production of Kander and Ebb musical Cabaret back in 2017.  It opened at the New Wimbledon Theatre and toured the country as well.  The production was Louise’s stage debut, while Will was reprising his role as the Emcee.  The musical stopped off in towns and cities across the country, including in Cardiff, Brighton, Salford, Malvern and Milton Keynes.  Speaking of her audition, Louise told the Telegraph at the time: “It was one of the scariest things I’ve done, and the most intimidating.”
