In a clip from tonight's show, Lockie blasts Gemma for texting Danielle, where she claimed he was dating a girl she hated.
Speaking to Pete Wicks and brothers Jon and Chris Clark in his new eatery Lockie's Kitchen, Lockie said: "I don't really know where Gemma's coming from with throwing up these accusations when she hasn't really got any evidence.
"I don't know why she's involving herself. Especially sending her a text message, it wasn't exactly a nice message. It was quite malicious, as if she was half laughing, making a little dig."
On Sunday's episode, Danni received the text from Gemma, which left her in tears.
Gemma's text read: "Babes, sorry been avoiding you since my party. I didn't know at the time but Lockie has been seeing that girl from my party, the one you hate… I wanted to let you know cause everyone in Essex is talking about it. Can you pop in the shop soon? X"
In tears, Danni grilled Pete but he insisted he knew nothing about it. Danni then said that she thinks it could be a girl who is a friend of Kate Wright.
Danni went to confront Lockie, but he denied Gemma's claims that he was seeing anyone, and also told her that it wasn't any of her business anymore because they are no longer together.
"We aren't together, this is going to happen," said Danni. "You'll meet someone, I will meet someone eventually. I just feel it's really disrespectful to do it on my own door step."
Lockie replied: "I gave you an ultimatum a little while ago to get back with me and you said no, so as much as we have a lot of respect for each other, you don't really have a leg to stand on. With all due respect, it's none of your business but I'm not seeing anyone."
TOWIE airs tonight at 10pm on ITVBe.
