The source dished the deets on the surprise sighting on Saturday night, noting: "Channing was dancing and chatting with a friend while Zoe was enjoying the music."
But it was only days before the Miami bash that the 32-year-old actress had set tongues wagging when she was seen spending time with her rumored former flame.
As OK! previously reported, the Divergent star was spotted in L.A. with the Star Trek actor. Kravitz wore an oversized shirt paired with a trendy brown leather jacket, while Pine sported a similarly casual look with a scruffy beard, jacket, and jeans.
Shutterbugs snapped several pics of Kravitz and the Wonderwoman 1984 actor leaving a West Hollywood sushi bar after having dinner together. The duo lingered outside of the restaurant for some time for a smoke break, and reportedly seemed very relaxed and totally focused on each other as they chatted between puffs.
The pair parted ways after a sweet hug, then walked separately back to their own cars.
Though their meeting seemed to be an innocent dinner between old friends, once upon a time, the Hollywood A-Listers sparked rumors of romance when they were linked back in 2010 after attending several high profile events together including the Met Gala, as well as London's Fashion Week.
Regardless of the tender reunion, Kravitz and her hunky beau's relationship seems to be as strong as ever. OK! recently learned the Mad Max: Fury Road actress is slowly becoming a part of the family and was recently spotted bonding with Tatum's 8-year-old daughter, Everly.
“[It] only seems natural that she [Kravitz] is getting to know Everly” an insider spilled to PEOPLE, adding that the Logan Lucky actor “is a very loving dad” and “acts very serious with Zoe.”
