X Factor judge Mel was pictured arriving at the Katie Piper Foundation Ball with her hubby and posed for the cameras before heading inside the venue.
The former Spice Girl opted to wear a long satin dress to the event, held in London, and its racy strapless neckline left little to the imagination!
The fundraising evening was held by Katie Piper - who suffered horrific burns in an acid attack in 2008 - and it was to raise money and awareness for her charity.
Mel's boss Simon Cowell is a big supporter of Katie's and it appears he was the one who encouraged his colleague to attend the event and support Katie.
Earlier today (28 November), Mel took to Instagram and told her followers: "Thank you @SimonCowell for making me and hubby @stephenthinks11 about a great charity sooooo glad to be involved @katiepiper_ you're a true inspiration."
The Katie Piper Foundation supports burns victims through workshops and by offering people specialist treatments and therapies.
Mel's X Factor co-star Cheryl Fernandez-Versini also attended Katie's Ball last night.
