Megan has strongly denied the claims, using an insider exclusively telling OK! Online it is a “disgusting lie”, saying there are “no truth” in the rumours.
None of the claimed “evidence” was spotted, but a source told The Sun: “Liam hasn’t said what type of proof he has on Megan, but he’s determined it’s proof that she had been with Harry until she broke up with Pete.”
And during Sunday’s instalment of TOWIE, Pete addressed that the rumours as he collaborated with pals James Locke and Mike Hassini.
The star seemed to have choked up as he talked before making a massive revelation.
Pete claimed that this isn’t the first time that Megan has gone back to her ex and claimed that she slept with Harry after the first split of the pair.
He then hit out in his ex for having always brought up his sexting scandal, saying: “Every chance she has had, she has thrown me under the bus.”
Elsewhere, Megan also addressed the reports after a yoga session with her pals.
She explained that after their separation, she went out for dinner with Harry and had “a very great moment.”
The High Heeled Shoes singer defended herself, before adding that she is “only human.”
Will Pete and Megan ever have the ability to resolve their differences?
