The Skims founder and the 27-year-old funnyman were spotted on what looked suspiciously like "date nights" during an affection-filled week in NYC.
Witnesses at several New York City hotspots told TMZ the pair were "very comfortable" with each other and didn't shy away from "plenty of PDA."
Included on the invite list are KUWTK alums Kris Jenner and her boyfriend, Corey Gamble, but it appears her 41-year-old daughter will be flying solo when it comes to the wedding.
“[Kardashian] is not bringing Pete. She will be there solo,” an insider spilled to Page Six.
Kardashian filed for divorce from the "Gold Digger" rapper in February of this year. The A-List former couple share four young children — North, 8, Saint, 5, Chicago, 3, and Psalm, 2. She has yet to publicly date anyone.
