Once again, Emma Willis hosted the episode on Channel 5, which this time saw the series start with an all-female line-up.
Former Made In Chelsea star Ashley James entered the Borehamwood bungalow, alongside Boris Johnson's sister Rachel, and glamour model Jess Impiazzi.
Now, it is being reported that former Ex On The Beach beauty Jess split from her fiancé Denny Solomona ahead of her stint in the CBB house.
The 28-year-old starlet has revealed she's one to a new romance in the house, although she'll have to wait until Friday, when the men are set to join in on the fun.

The brunette bombshell revealed she and her rugby ace partner fell out of love when they weren't seeing each other often, and not getting on very well.
However, the reality TV babe insisted that there's no hard feelings between them both, despite the split.
Jess told The Sun: "We own two dogs together and two houses so I have to see him, it's not like I'll never see him again. There's no nastiness or anything and that's the main thing, I guess."
Jess also revealed that Denny text her to wish her good luck after finding out she would be entering the famous house, although it's unlikely he'll watch her.

She also revealed new love isn't out of the question, adding: "I am happy being single and doing my own thing.
"I've always been in relationships, but you never know when something comes along, do you? You can't pick or choose when that's going to happen, so who knows."
Jess and Denny began dating back in 2015, and the pair quickly moved in together.
They split up in June 2016, but reconciled and became engaged in November the same year.

Jess explained entering the house was too big of an opportunity to turn down, and said the experience is "surreal".
However, it will be hard for the glamour girl to spend time away from her mum, who admits the pair will find it difficult not speaking every day.
Jess told the publication how the pair speak on the phone four or five times a day.
