There's certainly lots of smoke. Sources on both Scottie and Larsa's side tell us ... she's been jumping on Future's private jet, traveling with him to various cities, including Vegas last month. Sources from both sides also say Larsa and Future were very "cozy" recently at Komodo nightclub in Miami.
We've learned they met in August at the Haute Living Color Reveal Party in Miami, and have been seen at various places ever since.
Our Larsa sources describe whatever's going on between Larsa and Future as "casual." They also say whatever is going on ... it started after Scottie was openly flirting with an actress last Summer, and she felt disrespected. Thus, revenge.
TMZ Sports broke the story, cops have been called to the Pippen house twice this month after heated arguments between the 2 erupted.
We're told both Larsa and Scottie agreed to a divorce several weeks ago, but then backed off. As we first reported, Scottie pulled the trigger this week.
