Last week, MIC viewers saw a distressed Andy speaking about his relationship troubles to friend Stevie Johnson, revealing that Louise had spent the night at a male friend's house without telling him where she was.
Andy explained that he had called and texted Louise throughout the night, but that she had not responded to his messages.
Speaking to Reveal, Binky said: "I was surprised by what Louise did to Andy, I was surprised that she stayed over. I saw Andy in the morning and he was in bits."
Binky now hopes that the pair can move forward in their relationship, but she did doubt them when they first got together because Louise had just come out of a turbulent relationship with Spencer Matthews.
"I hope Louise actually does likes Andy a lot, I'm sure she does," said Binky. "Everyone has their ups and downs and new relationships take a while to get into, especially after Spencer. I was worried it would be a rebound, but I don't think it is.
"They're still together and they're very happy now and hopefully that will continue."
Binky also touched upon Louise and Lucy Watson's dislike for each other. The girls have become firm enemies on the show, especially when Lucy began dating Spencer (although they have now split).
Binky added that she has found it "difficult" being friends to them both: "They both know I like the other one and they understand that, they don't bitch about the other person because obviously there's no point," she admitted.
"It has been quite difficult I guess, but I don't have to get involved, it's none of my business."
Binky has been working with Solero to promote the guilt free 94 calorie treat Solero Exotic ice cream.
