Michael Klim accuses ex Lindy of attacking his new partner before announcing her pregnancy.

Michael Klim and his partner Desiree Deravi have publicly claimed that they were being trolled by the former swimmer’s estranged wife, Lindy Klim.

The Olympian made the accusation over the weekend after an Instagram user with the handle j_cross1 left now-deleted comments on a number of Deravi’s posts. The latest, a snap that featured Michael and Lindy’s daughters.

“We know it’s you @lindyklim so just stop with the trolling it’s pathetic you’re a grown women and stop being so disrespectful [sic],” Klim wrote.

Deravi then stepped in when another user defended j_cross1 by suggesting that it “pulls at heart strings seeing your own children posted on social media when it’s out of your control”.

“If @michaelklim1 doesn’t mind and he is their father and the children don’t mind why should anyone else especially since @lindyklim has been blocked for trolling,” the fashion designer responded. “Let’s get one thing straight, making a fake account and TROLLING is never ok and these comments are not the first. It’s constant and inappropriate. Not mention the emails!” [sic]

Lindy Klim yesterday announced she is expecting her first child with her British property developer fiancé Adam Ellis.

The couple became engaged in October 2016, six months after she split from Michael.

Klim, who is poised to launch her fashion label, RAMA by Lindy, spoke in May of her desire for a speedy divorce from her estranged husband, so that she could “move on” with Ellis.

“I am ready for that to be over. It’s not a good thing to go through. We are just getting through it,” she told Fairfax Media.

The couple were married for ten years and have three children, Stella, aged 11, Rocco, nine, and Frankie, five.

Mamamia has reached out to Lindy Klim's management for comment but did not hear back by the time of publication.
