The alleged makeout session went down at Scheana Shay's wedding to Brock Davies in Cancún on Tuesday, an event that Katie did not attend.
"Apparently there was some heavy drinking involved. They made out,” a source revealed on Friday.
Schwartz, 39, and Raquel, 27, may not have stopped at just swapping spit. The insider told Us Weekly they heard “through the grapevine” that “more happened” between the pair.
Both were part of Scheana's bridal party — and their makeout might have been caught on film. As RadarOnline.com exclusively reported, Bravo cameras were rolling for Scheana and Brock's wedding.
Schwartz moves fast. Katie only filed for divorce in March. With their marital home finally selling, it looks like he made his move on the beauty queen.
While Katie wasn't in attendance, she was in the vicinity. Schwartz's estranged wife was in Mexico on a girl's trip and was absent from her co-stars' nuptials.
However, Raquel's ex James Kennedy was there and may have witnessed the alleged drunken smooches.
RadarOnline.com has reached out to Katie's team about the kiss.
