It all started when Chelsie commented on her Bachelor co-star Jessica Brody's Instagram photo where she's holding a rose.
"Me ➡️vs.➡️ Me when he tells me I’m the only girl he’s talking to🌹" read the caption.
Chelsie commented on the photo with a VERY pointed statement: "triggeredddddd'.
Adding fuel to the fire, Chelsie's good friend who was also on the show replied.
"@chelsiemcleod Bahaha haahahha when u can finally say triggred as well. ytg"
Chelsie replied, "@rachaelarahill triggered is an understatement tbf."
These shady comments aren't the first that both Rachael and Chelsie have made following the split.
The first came from Rachael, who basically confirmed that Matt did the dumping.
After the break up was announced, a fan commented: "omg no, I wanna know why 😭."
"So does Chelsie," replied Rachael.
While Chelsie has stayed pretty quiet after the breakup, she recently posted a photo of herself, Nichole Wood, Helena Sauzier and Sogan Moffat from the show, she captioned the photo: "Take the good with the bad".
Clearly, Chelsie is referring to her newfound friends as the 'good', and her sh*tty relationship with Matt as the 'bad'. But hey, one can only assume.
The former couple announced their split last weekend (November 17), with Matt admitting it was "with a heavy heart" that he'd parted ways with Chelsie.
"These past six months since filming have been a very unique experience. Chels and I have made some beautiful memories together that I’ll always cherish, and I wish her nothing but the absolute best. However, it’s with a heavy heart that I write this. For Chels and me, our relationship hasn’t translated from filming to the real, every day world as we had hoped."
He continued: "Chels is a very special woman and I want her to find the happiness she deserves. For those who may wonder if there’s someone else for me right now, there absolutely is not. It’s no one’s fault, it’s just life."
Shortly after, Chelsie posted her own announcement.
"Thank you so much to everyone for your support and kind words over what was an incredibly exciting, rewarding, challenging, and emotional journey," she began. "Your words have not gone unnoticed. Matt showed me what it was like to be respected in a relationship and I am so thankful for that. However, it saddens me to say that we are no longer together.
"I wish him nothing but the best. I’m sorry to those that were invested in our relationship. Please remember to be kind online as you don’t know what is going on behind the screen. All my love."
