The Charlie's Angels actress was snapped throwing some serious shapes at the Chanel beachside BBQ at Soho Beach House last night (5th December) - sporting her trademark smile again for the first time in months.
Moore narrowly avoided a wardrobe malfunction as she danced in a short, grey jumpsuit - at one point, even hiding behind her long, dark hair.
Following the end of her six-year marriage to Kutcher - who is now dating Mila Kunis - Demi was said to have entered rehab after collapsing at her home.
A rep later confirmed that she was "seeking professional help" for exhaustion.
Judging by her antics last night, it seems Moore is back on track, with reports last week even suggesting she's bagged herself a new toyboy.
The 50-year old is said to be dating art-dealer Vito Schnabel, with source telling The Sun they have been "quietly spending time together” since meeting in early November.
