In a lengthy statement on social media, which was made in the lead up to tonight's show, Chloe described Lillie as "lovely" and insisted it was never her intention to cause any hurt.
However, although she has promised to "have Bear's back 100 per cent", Chloe admits Bear did tell her he was single when they both entered the house.
Chloe said: "I'm glad that Lillie went into the house. It's finally shown the sensitive emotional side of Bear that I saw and loved all the time I was there.
"Lillie seems lovely and I have never wanted to hurt anyone. He said she was finished and [that they] only dated for a few weeks.
"I was single when I went in the house (read that I'm married - not true)."
She continued: "In the house, everything is so intense. It feels like we were there forever and Bear and I were so inseparable. But out here we have different lives.
"He asked me to wait for him and I am, but whatever happens with us is cool and I will always have his back 100 per cent. #Bearwinner2016."
Viewers were gripped tonight as Lillie entered the CBB house as a 'distraction', while Bear balanced three doughnuts on his head.
She tearfully told him: "This is the hardest thing I've ever had to do, I just needed to see you… it's so surreal… I'm having to watch this from home. You had me with you until the car came to collect you; you left me with your family. You asked me to be there when you got home, I was supporting you 100 per cent. The embarrassment and humiliation I've had… this is all one big game to you, it is a joke at my expense."
Although he remained silent at the time, Bear broke down in the Diary Room and even admitted he would have "married" Lillie.
Despite this, Bear later told Ricky Norwood that he wanted to see Chloe again and pick up where they left off.
Meanwhile, Lillie has received a huge amount of celebrity support after her surprise CBB appearance.
CBB continues at 9pm on Channel 5.
