The former Ex On The Beach star, 23, has been confronted with a string of rumours since joining TOWIE in February, all of which threatened to rock her solid relationship with Pete.
So, who better than family to offer advice?
Viewers met Megan's parents, Dave and Tanya, and 17-year-old sister Milly on Wednesday night (27 July), as she filled them in on everything that's been happening lately.
And can we just say, how awesome are Mr and Mrs McKenna? More of them on screen, we say!
Megan told her family: "Obviously there has been drama…" Her mum interjected to quip: "There will always be drama with you, Megan!"
"The reason I get so angry and defensive about these rumours," continued Megan, "is it's to do with my relationship and I really care about Pete. Everyone thinks I'm going crazy for no reason but I'm not!"
Her dad Dave replied: "You take after me, Megan."
Mum Tanya then offered some sound advice to her daughter: "Of course, you're going to defend yourself. It's natural you will defend yourself. You just have to do it in a better way. Take a deep breath, think before you talk and don't let them rile you like they have been."
Sister Milly added: "They are looking for a reaction and the fact you're giving it to them, that's what they want. They want you to look bad."
Megan admitted Pete doesn't like it when she loses her temper, prompting her father to reply: "And you have been doing that quite a few times lately…"
Just a few!
"I'm just lucky he stands by me," said Megan. "I think if I had another asshole Essex boy, like I've been with in the past, they would have been long gone by now."
And Pete definitely isn't like that: he's had Megan's back since day one, constantly defending her against criticism and vowing they are a "team" and he "100 per cent" trusts her.
He also has the seal of approval from her family, who all said last night how much they liked him. "It's probably the first time I've really liked someone!" added mum Tanya.
Can we just say, more McKennas please in future episodes!
