Kristin Cavallari says there was absolutely NO scandal involving Jay Cutler that led to their divorce ... with the reality TV star insisting the marriage point-blank "just didn't work out."
The celeb couple announced their split back in April ... and it came as a shock to most -- considering the duo seemed publicly happy.
But, in an interview with People this week, Cavallari insists everything fell apart because the two grew apart ... adding "there was no real drama."
"I met Jay when I was 23," Cavallari said.
