Hell hath no fury like a woman scorned — a lesson Robby Hayes is definitely learning. The Bachelor in Paradise star was just seemingly dissed by ex-girlfriend Amanda Stanton in an episode of the Will You Accept This Ride? YouTube series.

The 27-year-old was very candid throughout the interview, and didn't hold back when she found the opportunity to take a little jab at her ex. When asked who had the worst breath out of the entire Season 4 cast, the Bachelor alum was quick to respond, “Robby.” Realizing she could cause some controversy with that response, she followed up, “He’s the only one I got close enough to. He wasn’t bad, but…”

This isn’t the first time the former couple went public with their bad blood. After the 28-year-old hunk was called out at the BiP reunion for allegedly cheating on the blonde beauty, he took to Twitter to defend himself — and attack Amanda.

“I’ll never understand why there's such a desperate need to present an ‘innocent persona’ and resort to allowing allegations that are blatantly untrue be said about me by ‘the twins’ while one sits back and ‘unknowingly’ watches these malicious attacks continue against me,” he wrote in the lengthy post.

However, Amanda was quick to put the reality star in his place, sharing a photo of Robby getting a little too cozy with an unknown woman, along with the cryptic caption, "Look what you made me do."

The California beauty has never been afraid to speak the truth about her famous exes. In June, she confessed how “grossed out” she was by “sweaty” ex-fiancé Josh Murray — even in the moments after they got engaged during the Season 3 finale.

“I remember at the end [of Paradise], I was trying — like I was really happy, but he would like, hug me and I was kind of grossed out," she said at the time. “His shirt was soaking wet.”
