Nanny Pat has suggested that Arg still has feelings for his ex-girlfriend Lydia, despite dating Gemma.
Arg and Gemma's relationship has been patchy at best, with numerous rows in recent weeks.
Speaking to Star magazine, Nanny Pat branded Gemma a "lovely girl" but was unsure about Arg's real feelings for her.
"Whenever we're on set, Gemma will always say hello and give me a kiss. She's a nice girl. We have our chats," she said.
She added: "He shouldn't care what size Gemma is - she's a lovely girl. And then it came out she might be pregnant! I thought 'Oh come on, Gemma - surely not?'"
But Nanny Pat reckons that Arg still has some feelings for old flame Lydia Bright, even if she may not feel the same way.
She suggested: "I think he still has feelings for Lydia.
"I don't think she does for him, she wants to get on with her own life, but Arg won't leave it alone."
The Only Way Is Essex continues Wednesdays and Sundays on ITV2.
