An Eye-Witness Report
"I was there and he was on the table right next to us with a group of friends and some girl who he was obviously making out with all night," the person who recorded the video tells TMZ.
An "Obvious" Affair
"They were holding each other and it was so obvious," the onlooker adds.
TMZ even claims to have footage of Tristan and the woman entering Manhattan's Four Seasons hotel at around 5 am. We're guessing Khloe would prefer not to know what happened next.
A Mistress Identified
TMZ also claims to have identified the woman as an Instagram user named "@ms.stephaniee_". And it seems she's got some bombshells of her own to drop.
Not Playing Games
Not surprisingly, Stephanie has deleted her Instagram account, likely in response to a barrage of negative comments from Khloe's fans. First, however, she posted what appeared to be sex tape footage. The clip was deleted just minutes later, and it's impossible to tell who her partner was.
You're Not the Only One, Khloe
Before deletng her account, Stephanie posted this scandalous message claiming that she's also pregnant.
