Danni and Lockie split last year and have remained friendly, but Danielle has admitted in recent weeks it's difficult to watch Lockie possibly moving on.
She was left hurt this series when Gemma Collins text her to say Lockie had been seeing another girl – someone who is friends with Kate Wright – but Lockie and the woman denied it.
Then, on the most recent episode, it emerged Georgia had heard a rumour that Lockie had slept with newcomer Courtney, so she decided to get to the bottom of it.
Speaking to the official TOWIE website, Georgia said: "I would definitely want to know. Last year she came up to me without knowing any facts, just that people were talking about it. I would definitely have told Danielle way before this conversation today but because she fully said she doesn't want to know unless it's the truth, that's why it's through me."
"We need to get the facts. Obviously she got hurt last week when Gemma Collins threw in a bombshell so I feel like if that didn't happen it would be easier for me. I don't want people talking about it and Danielle being the only one who doesn't know. She has to know before everyone else does."
"It could be a rumour. If it was a random girl, then it's like whatever, he is single I get that. But it's the fact Courtney came in and said she was a girl's girl, never mentioned Lockie trying with her, now she's saying Lockie asked to kiss her which makes me think what else could she be hiding?" continued Georgia.
"It could actually be true. I hope it's not for Danielle's sake but I feel Danielle has a right to know as this girl is getting closer in our group."
But when Georgia confronted Courtney, Courtney denied it was true.
"I've just never heard a rumour like that about me that is not true whatsoever, it shocked me," said Courtney. "I was speechless, like, where did this come from!? I have so much respect for myself that I don't just sleep with anyone."
She added: "I haven't even kissed him, I don't have his phone number. The most I do is follow him on Instagram!"
