The ex-model told The Sun that she was unaware the mirrors in the CBB house were two-way and she'd never intended to flaunt her breasts for the camera.
Alicia said: "I was telling Katie and Michelle about my boob jobs, and how one is rock hard and the other isn't. So Katie, who is very intelligent, said: 'Let's have a look.' I didn't realise at the time that the mirrors in the house are two-way and the next thing I know I've got my boobs out on TV."
The 36-year-old said living in the house with Katie had been challenging, describing it as a "game of chess".
"That day she outplayed me by using my openness against me," said Alicia.
"She was always trying to gun for a fight with me, because she knew I would rise to it, even though at the end she said she respected me because she felt I would bite back."
Alicia was evicted from the CBB house on Friday night, after facing the public vote against Perez Hilton, Nadia Sawalha and Calum Best.
Surprisingly, after her eviction, Katie admitted she was cross to see Alicia go as Alicia had no gameplan and had been a genuine person.
"I'm cross that Perez is still here. I'm cross that my sparring partner has gone. We had banter. And it was funny. And she was such a loon. She had no gameplan. She was literally being her. There is a limited number of her in here in that regard."
