Unsurprisingly, given their bitter split, Cami, 28, wasn't full of joy for the 27-year-old former TOWIE star.
Speaking to the MailOnline, Cami said: "You know what? Congratulations. Good for him. Maybe now he'll learn to be an adult."
CBB star Cami and Kirk both took part in the latest series of MTV's EX on the Beach, and she admitted she only signed up to get revenge on him.
She continued: "I decided to go on this dating show because in the back of my mind I knew he would be there and revenge is nothing but sweet.
"For two years he's been spreading lies about me. I left everything back home in Miami to be with this douche bag. Do you know what? He can go and f*** himself! I did not sign up for this show because I want to get back with him. I am here because I want revenge and I am going to get it."
We're sure Cami's words won't bother Kirk too much, as he's too busy gushing over his unborn baby girl on Twitter.
After insisting that Holli's pregnancy is the 'proudest moment' of his life, Kirk shared an adorable snap of him kissing her stomach.
He wrote: "Friday night in with my little girl! [sic]."
