“I got a cab from Manchester to the address and a driver picked me up outside and took me to the gates of his apartment.
“Then his friend came out and met me.
“There was another girl in the car too.”
Walker tried to keep his identity secret but after the girls went for a cigarette on the balcony, the other told Louise “Kai” was a “soccer player”.
Louise said: “I didn’t know who he was at the time.
“But I took a few photos of him.”
The men agreed to pay the girls £2,200 in cash before moving through to the bedroom, where Walker, 29, pulled out some gold-coloured Shine condoms.
Louise and the other girl left the apartment at around 2am on Wednesday.
Later that day, Walker told fans in an interview: “Stay indoors, keep washing your hands, keep following the protocols and just protect the NHS.
“It’s been tough, but first and foremost, we have to think about other people’s health and protecting the elderly and family members that can spread it.”
Days earlier, he posted a video message on Instagram for his 1.7million followers in which he encouraged fans to abide by the advice.
He put out similar Twitter messages.
Louise added: “Kyle really should know better.
“On the one hand he’s inviting strangers round to his house for sex, and the next day he’s lecturing everyone on the need to stay safe.
“He’s a hypocrite and putting people at risk.”
His behaviour is also likely to infuriate England manager Gareth Southgate.
In a statement last night, Walker said: “I want to take this opportunity to issue a public apology for the choices I made last week.
“I understand that my position as a professional footballer brings the responsibility of being a role model.
“As such, I want to apologise to my family, friends, football club, supporters and the public for letting them down.
