A British soldier who unsuccessfully tried to murder his army officer wife — by sabotaging her parachute during a 4,000ft jump — was swapping messages with his mistress while his spouse was in surgery, prosecutors said Monday.

“Will you be my cleaner? I only like nude house cleaners. I pay with hugs and kisses,” Sgt. Emile Cilliers told his lover, Stefanie Goller, as his wife was fighting to survive.

“Haha, I like naked cooking ; ),” he added, according to prosecutors.

The messages — sent through the WhatsApp service — were read to jurors on Monday, the BBC reports.

Cilliers, 37, is accused of tampering with the parachute that his wife, Victoria Cilliers, was using during a jump at a Wiltshire airfield in 2015. Prosecutors claim he tried killing her because he wanted to start a new life with Goller. They argue that the WhatsApp messages prove this.

“One day we might have a family of our own,” Cilliers told Goller, just as his wife was going under the knife.

In another exchange from a later date, the pair made sexual jokes about Cilliers being in the Royal Army Physical Training Corps.

“I love you in uniform ;)” Goller said to Cilliers.

“You going to salute me?” he asked her in response.

“I guess sometimes I will have to obey you ;)” she said.

Cilliers is also accused of trying to kill his wife in the days leading up to her military jump by tampering with a gas valve in their home.

Prosecutors read messages in court Monday that she sent before the fall, in which she flat-out questioned him about his alleged actions.

“Did you alter the gas lever into the cooker. It’s in the cupboard. Smell gas in the cupboard this am and dry blood around the lever!” Victoria said.

“Nope. That’s weird!” replied Cilliers. “Is the stove working?”

“Don’t want to try!” said Victoria.

Questioning her about her suspicions, Cilliers then wrote: “Hey. You…can’t be serious about the comment you made You have been saying that a lot recently. Why?”

In response, Victoria said: “Of course not! Just an article I read in a mag recently. Brought it to front of my mind…’True life reader stories. My husband tried to kill me.'”

Cilliers has denied the charges against him, which include attempted murder and tampering with a gas valve. He is expected back in court on Tuesday.
