The Spice Girl — who also showcased a brand new shorter haircut — relied on stick-on jewels cover up in the sheer number, The Sun reports.
The 42-year-old seemed in good spirits as she mucked about for red carpet snappers, performing lunges in the glorified body stocking, but managing to avoid a wardrobe malfunction.
As part of her dramatic new hairstyle, Mel’s head has been shaved on the right-hand side with blonde highlights streaked through the remaining hair.
On the America’s Got Talent live shows, Mel was joining pal Heidi Klum, Simon Cowell and Howie Mandel, all acting as her fellow judges, as well as presenter Tyra Banks.
Mel, who is in the middle of a divorce with ex Stephen Belafonte, recently started dating a Beverly Hills cop amid reports he helped her “stay strong” after her split.
Meanwhile it’s been revealed that the 90s icon did make a sex tape of herself, Stephen and their nanny Lorraine Gilles, who she previously accused of falling pregnant by her husband.
Lorraine is suing for libel and breach of privacy after being dragged into the divorce row.
The nanny, whose lawsuit testimony runs to 128 pages, denies getting pregnant and accuses Mel of falsely portraying her as a “conniving and backstabbing home- wrecker”.
But she’s also attacked Belafonte, saying he forced employees to watch ISIS beheading videos and splashed huge amounts of cash on tattoos.
Matters of money have also been rowed over in the divorce battle so far.
Mel has been revealed to have blown her Spice Girls fortune and was thought to have begged mates for cash so she could buy a post-split mansion to live in.
She is currently paying over $40,000 a month in spousal support to Stephen, who is a US film producer.
