"My lips are sealed on that subject," the Dynasty star replied. But it was what she said next that could be interpreted as an epic burn towards Morgan.
She added: "I just don't want to go on national TV and say what I think about Meghan and Harry, because look what happened to you."
Morgan appeared to read into her comments as support of his own views and replied: "Exactly - thank you."
The controversial presenter claimed earlier this week it was not his comments about the Duchess of Sussex that got him fired.
"ITV didn't get rid of me. I left GMB because I declined to apologise for disbelieving Princess Pinocchio," he shared on his Twitter account and plugged his interview with Collins which aired on the network.
The 55-year-old broadcaster clashed with his former co-host Alex Beresford on Good Morning Britain following the Duke and Duchess of Sussex's interview with Oprah Winfrey.
After a staggering 40,000 complaints about his on-air comments, where he downplayed Markle's mental health struggles, he resigned from the talk show.
