Demi Moore was a very busy woman this past Wednesday night (Dec 5).

At a private event at Alex Rodriguez’s house for Art Basel week in Miami, the 50-year-old actress showed up “dressed in a short blueish-gray romper and funky black glasses” and was described by sources as “calm, friendly and relaxed.”

“She didn’t even have a drink in hand,” one source told People of Moore, who reportedly spent most of her time at the party conversing with folks like Owen Wilson, Martha Stewart and her “good friend” Stacey Keibler.

But when the A-Rod party shut down at around 10 pm, that’s when Moore headed to the Chanel Beachside BBQ at the Soho Beach House and really started to loosen up.

“Demi seemed to be dancing for the cameras,” one party source said of the actress, who was surrounded by flashbulbs and was “acting flirty” with Lenny Kravitz. Another source at the party said Moore was drinking Red Bull, and: “Demi was wild and crazy and having the time of her life, in a world all of her own.”

Demi’s rumored boyfriend, 26-year-old art dealer Vito Schnabel was also at the Chanel BBQ, and even though the pair chose not to pose for any photos together, partygoers say the two didn’t hide their PDA and were spotted publicly making out. An eyewitness told E! News:

“They are definitely a couple. She is definitely more down to party than Vito. She was most ready to party than anyone else in the room.”

E! later updated their report with the following:

Despite their PDA and frequent time spent together of late, Schnabel told reporters in Miami that he and Moore weren’t dating and another source told E! News they were “just friends.”

No word on what exactly she was twerking to, or why … but we guess mama’s gotta get her swerve on too, y’all.

Sidebar: Demi looks pretty damn good for 50 years old!! You know, minus the awkward dancing.
