In an interview with The Sun, Charlotte accused Gaz of two-timing on his girlfriend with her, revealing: "[Gary and Lillie] had been together while he was still having sex with me."
Lillie took to Twitter (19 May) to respond to the rumours, revealing she's "taking no notice".
"Gary and I are very happy and I trust him implicitly. We travel everywhere together and are virtually joined at the hip. I'm very happy and excited for our future.
"I am always prepared for these kind of stories with Gary's history and his on screen story lines. However, I'm taking no notice xx"
Adding "That's all I have to say... ", it seems Lillie is rubbishing Charlotte's comments as "stories".
Gary revealed earlier this year that he'd given up his lothario ways, and he's seemed loved-up with Lillie ever since.
Will Char respond to the response?! This could all get very confusing...
