Los Angeles - Jennifer Lopez and Maksim Chmerkovskiy enjoyed a "very flirty" night out this past Saturday.
The Dancing With the Stars performer was spotted celebrating with the Booty hitmaker - who recently ended her relationship with 27-year-old dancer Casper Smart after two-and-a-half-years of dating - at Shrine nightclub in Ledyard, Connecticut after her concert at the Foxwoods Resort Casino.
An eyewitness told UsMagazine.com: "Chmerkovskiy was whispering into her ear and hugging her. They looked very flirty with each other...She had a huge smile on her face and looked like she was having a great time."
The duo recently denied they're dating, but the 34-year-old dancer remained by the 44-year-old beauty's side for most of the night.
The source said they held hands, talked and shared a long hug at the end of the night and before they left separately with different friends.
The First Love singer danced with Chmerkovskiy - who previously dated Kate Upton - at the American Music Awards last November and they were "inseparable" at his brother Val's birthday party in Los Angeles in March.
But a source close to Jennifer - who has six-year-old twins Max and Emme with ex-husband Marc Anthony - insisted she and Chmerkovskiy are still just friends for the moment.
The insider said: "They are friends. She doesn't have a second to date anyone right now, and it is definitely not romantic with Chmerkovskiy."
