To spark further speculation, Larsa was spotted wearing a ring on THAT finger ... although it's unclear if it's a legit engagement ring just yet. It's worth noting -- Pippen has worn the ring in a few recent Instagram posts as well.
It may be MJ's worst nightmare -- remember, #23 famously said he did NOT approve of the relationship while leaving a restaurant in Paris last month.
Larsa and Marcus later addressed the clip ... with Scottie's ex claiming MJ's comments left her "embarrassed" and "traumatized," and the latter insisting his pops gave his blessing ... but didn't want to fuel speculation their relationship had anything to do with his infamous feud with Michael's longtime wingman.
Regardless of what the Hall of Famer thinks, Larcus were inseparable at Drizzy's show earlier Wednesday evening ... with Pippen grinding all over Jordan throughout the night.
Fittingly, Marcus' shirt read, "Hug me I'm horny!!"
