Comedian Celia Pacquola jumped straight into the roast when she brought up Matt's infamous dry humping scene with the 23-year-old property analyst in the penultimate episode.
“At what point in the series, Matt, did you think Chelsie was the one?” host Tom Gleisner asked the astrophysicist.
“Certainly popping the oxytocin tattoo on my chest made an impression,” he said, to which Celia replied: “Was that before or after that beach thing that we saw?”
As the room erupted in laughter, panellist Ed Kavalee sarcastically added: “Excuse me, Matt has a very simple and believable explanation for dry humping a woman the day before he picked someone else.”

Looking more and more awkward as the savage remarks increased in intensity, a less than impressed Chelsie didn't take too kindly to Ed when he guessed Abbie's name was engraved on the necklace Matt gave to Chelsie during their final date.
Barely given a minute to process what he said, Matt was forced to ask the panel: “For The Bachelor finale, I took Abbie and Chelsie somewhere special. Where did I take them?”
While Ed correctly answered "South Africa", Sam Pang came in hot with a pretty decent zinger.
"You took Abbie as well? You took Abbie to South Africa to dump her? Why didn’t you just take her to Nando’s like Ed (Kavalee) does? Unbelievable," he joked as the audience howled with laughter.
The most savage dig came right before the segment wrapped when Matt asked, "On Thursday I said goodbye to Abbie. What were her final words to me?”
"I'm pregnant," Celia joked.
She followed up with, “She said, ‘As long as you’re happy, that’s the most important thing’, which is bulls**t. It sounds lovely but then I watched it and it was quite angry.”
"Get over him," Kyle told Abbie. "Because I asked those two this morning what the sex was like. They were on a couch in a hotel in South Africa making out and feeling each other, and then he lifted her up and took her to the bedroom, took all his clothes off and inserted himself... You need to move on as well."

After a brief moment of silence, she could be heard crying on the other end of the phone.
"She didn't need to hear that," Jackie O said to which Abbie replied, "Umm... sorry."
"Good one, Kyle," Jackie said awkwardly as the radio shock jock desperately tried to defend himself by saying: "It happened months ago!"
After Abbie hung up, Kyle appeared to feel horrible about the conversation, admitting: I didn't mean to make her cry. I was trying to help her get over it… In hindsight, you're right. I don't like when girls cry."
