Phillipa Copleston-Warren, 45, allegedly told the sobbing girlfriend to leave the house through the voice-controlled device and flashed his house lights off and on.

She also accessed her ex’s Facebook account and posted nude photos of him, leaving him feeling ‘violated’, it is claimed.

The businessman was at his Lincolnshire home at the time with a female friend after recently splitting with Copleston-Warren after a two year relationship.

Copleston-Warren appeared at Isleworth Crown Court via video-link from home, speaking only to confirm her identity and deny disclosing private sexual photographs and films with intent to cause distress.

Misba Majid, prosecuting, earlier said: ‘On October 5 the victim had returned home to the property with another female.

‘Somehow the defendant had managed to hack into the complainant’s Alexa whilst they were at the property.

‘The defendant spoke through the Alexa account to tell the complainant’s friend in the property to leave and to take her stuff.

‘She also used the Alexa to turn the lights on and off. This so distressed the individual it caused her to cry and she left.

‘Later that day he received various different text messages about how the defendant was going to disclose photos, naked photos and upload them to his Facebook.

‘The defendant had hacked into the Facebook account and changed his password. She then sent text messages informing him that she had uploaded photos.’

Copleston-Warren allegedly said he had fathered two children out of wedlock on his Facebook account.

Judge Sarah Paneth told Copleston-Warren she would stand trial in August, adding: ‘Your trial date is very soon in fact, compared to many other people who are on bail.’

Copleston-Warren, of Paultons Square, Chelsea, denies disclosing private sexual photographs and films with intent to cause distress.

She was granted bail on condition not to contact the man or visit his Lincolnshire home ahead of her trial at Isleworth Crown Court on 23 August 2021.
