The only thing Larsa Pippen appears to be sweating this week is the sun -- as she looked totally unbothered by Marcus Jordan's recent Miami flings in a bikini pic she posted on Monday.
Just hours after it was revealed Jordan -- who dated Pippen for years -- had not one but two PDA-packed beach sessions with separate women over the weekend ... Pippen took to her IG page to show she's doing just fine despite her ex's antics.

In the snap, Larsa could be seen in a tiny white two-piece laying out on a lounge chair in the backyard of a home.
