Jacqui has accused Pete of messaging her behind girlfriend Megan's back in an interview with The Sun. She told the paper she "feels sorry" for Megan over the alleged texts and claimed Pete could "potentially really hurt her."
However, Megan has now hit back at Jacqui and questioned why she decided to not privately contact her.
In a series of tweets, Megan said: "@JacquiRyland feel sorry for me do ya? Why didn't you personaly contact me then you fame hungry brass. I've seen it all. Didn't feel sorry for me while you was sending dirty messages back did ya? Or selling the story to the paper. (sic)"
So far, Jacqui hasn't responded, while Pete hasn't commented in response to his ex's claims.
A rep for Megan declined to comment when contacted by Reveal. We have also contacted a rep for Pete.
TOWIE's official Twitter account, meanwhile, suggested Megan has now confronted Pete about the claims. They tweeted: "JUST IN from the #TOWIMGrass: It looks like Megan's confronting Pete about *those* rumours that emerged this morning."
It's reported Pete and Jacqui dated at the beginning of this year, before he got together with Megan. Jacqui claims she got back in touch with Pete, following the death of his dog Ernest, and has said she was "shocked" by the X-rated messages he had sent her. She claims Pete had text her while holidaying in Barcelona with Megan and during the TOWIE cast's trip to Marbella.
She claimed: "He was doing the public affection thing with her and then sending me these messages... I always thought he was a really nice guy who was respectful to women. I was attracted to his banter. I just feel really sorry for Megan. Clearly she is a girl who wears her heart on her sleeve and I think he could potentially really hurt her."
Just days ago, Pete had been gushing about his relationship with Megan on social media. He tweeted: "We are a misunderstood couple but I can't put in to words how lucky I am to have a bird that stands by me like she does...@Megan_Mckenna_."
The pair have been overseas filming for TOWIE in Marbs and had looked nothing but loved-up, celebrating Megan's birthday together. Pete had surprised Megan with a huge bouquet of flowers and a Rolex watch, prompting her to say on Instagram underneath a photo of her gifts: "I can't explain what an amazing boyfriend I have! This has been the best birthday I've ever had and I can't get over how much this boy has spoilt me.... Im speechless! I love you."
Pete, meanwhile, credited Megan for making him a "better geezer."
They first began dating at the end of February, earlier this year, and fans later saw Megan join TOWIE alongside Pete, with the couple making their romance official onscreen.
