The incident led to her arrest and charge with battery. Later, the charge was reduced and eventually dropped in 2017. During an interview with Starry Mag, Chastain regretted her relationship with her ex-girlfriend on Below Deck, saying:
While I didn’t let my personal life get in the way of my job as Chief Stew, I do wish that I had not given in so much to the demands of my significant other at the time to stay in such constant contact. It really added unnecessary stress to my already stressful life onboard, and I think it kept me from bonding with my fellow crewmembers in our downtime.
She added:
At the time, I was just trying to keep the peace, so I didn’t return home to anger, but I’ve since learnt that significant others should only be supportive rather than temperamental and that sometimes keeping the peace is an unhealthy sacrifice.
The reality TV personality was also rumoured to be dating her Below Deck castmate Josiah Carter. She even referred to Carter as her work husband on Watch What Happens Live with Andy Cohen, but she clarified that they had a platonic relationship, and they remain good friends even after the show.
Chastain was also romantically linked to American master chef Ben Robinson. The duo sparked romance rumours between Seasons 2 and 3 of Below Deck, and while they have not admitted to having had a formal relationship, they alluded to having hooked up at least once.

I will admit, and you know, up until this point, especially from what people saw on Below Deck, I was used to being in charge and knowing what I was doing.
