The Spice Girl joined her A-list pals at London nightspot Annabel's for the launch of its forthcoming documentary, A String Of Naked Lightbulbs.
One to love a cheeky selfie, Mel just couldn't resist grabbing a quick snap of herself and her table of famous faces before sharing it with fans.
Is that Grimmers we can spot squeezing in next to Mel?
While Mel pouts like a pro in front, Harry is playing up to the cameras by pulling a silly face. And Kate seems oblivious that a photo is even being taken...
As well as her showbiz friends, Mel was joined by Stephen Belafonte - her husband of seven years - at the event.
Looking super-glamorous, Mel dressed up for the occasion in a stylish, wrap-over black playsuit. Putting her enviable pins on display, the 39-year-old teamed her outfit with a pair of barely-there sandals and a chunky rose gold watch on her wrist.
Mel added a burst of colour to her ensemble, matching her bright red lipstick to her nail polish on her hands and feet.
The talent judge's fun night out comes after Mel was left teary-eyed following Jake Quickenden's X Factor exit on the weekend.
Finalist Jake was voted out of the competition by the judges, following his sing off with mixed group Only The Young.
Explaining why she struggled to hold back her emotions, Mel said: "You get so attached to these guys... They're like my kids, my family... I know it's a competition and someone has to go every week, I get it, but it still [stabs] you in the heart."
This week, Mel will join her remaining three acts - Jack Walton, Paul Akister and Andrea Faustini - as they take to the stage for the fourth time for the Halloween-themed live show.
The X Factor continues this Saturday and Sunday (1-2 November) at 8pm on ITV.
