Is Maksim Chmerkovskiy Jennifer Lopez's Boyfriend? -- Does It LOOK Like They're Dating?

Maksim Chmerkovskiy wanted to make it skin clear -- he's NOT JLo's newest accessory.

Maksim was all over the Hamptons during the 4th weekend -- hitting up Nammos on Friday night and The Surf Lodge on Saturday. Maksim and the buttons on his shirt clearly had a falling out.

Maksim made it clear to everyone who looked ... he's not dating Jennifer Lopez -- even though he himself stoked the coals.

Maksim was repeatedly seen with fitness model Alesya Bikeeva -- posing with her and later taking mirroring pics next to a jeep.
