Larsa Pippen Parties Hard on Birthday Weekend with Boyfriend Jeff Coby

Larsa Pippen‘s partying her 51st birthday weekend away … getting close with her man Jeff Coby at a Miami club — and, their relationship sounds super serious.

The reality television star hit up E11EVEN — a multilevel nightclub in the downtown area of The Magic City — around 1 AM Thursday morning … bringing a whole entourage with her.

Larsa started her night on the red carpet with some ladies and then with Jeff — before hitting the dance floor for a few drinks, a little dancing and a whole lot of birthday well wishes.

Cameras were flashing all night capturing pics of the birthday girl … who revealed to People that she and her boyfriend have talked about taking the next step in their relationship.

Larsa told the outlet she and Coby have discussed engagement rings … not size, necessarily, but certainly the cut of the diamond — revealing she likes brilliant cut and opal diamonds.

Pippen says she thinks she and Jeff are “on a really good path right now” … so, don’t be surprised if wedding bells are in their future.
