The sources tell TMZ, she has had NO contact with Lamar for weeks and in fact changed her number a few weeks back and never gave him the digits.
TMZ broke the story ... Kardashian sources and eyewitnesses at SoulCycle Wednesday claim Lamar surprised Khloe on her way in at 6:45 AM, began shouting at her and put his hands on her shoulder before she told him to get away. Khloe jumped in her car and beat it.
Lamar told TMZ he and Khloe had communicated before the meeting and said it was absolutely not an ambush. But our sources say in no way did she invite him there and she had no idea he would be there.
We're told Khloe does not feel physically threatened, but says she's concerned for Lamar's well being.
