She said, “Another fun fact is that I was an extra in two of the Harry Potter movies, but I was also a quidditch player for the Gryffindor tryouts, so I had a double and all.

“I have to go to the set and look at the green screen and go to the quidditch ground.

“It was part of my full-time education, I went to theater school and we all had to study there and go to set and film.

Megan recently had her followers in on her TikTok debut, recreating her iconic tantrums from her time on Celebrity Big Brother.

She dressed up in a tracksuit, earrings and a camouflage-print baseball cap, trying to emulate her former wild-child self, while participating in a recording of one of her diaries in the diary room.

Mascara ran, she raved about the food she got, which happened during her stay at the famous BB house during the 2016 season, which turned out to be one of the most iconic of all time, with the infamous David’s Dead mix.

She was spotted hissing while asked to eat ‘crackers and figs’ while rationing.

“I can’t eat that, damn it!” she screamed.

Big Brother’s voice was then heard and said, “Megan, the meals Big Brother provided during the task are nutritionally balanced.”

To which Megan replied, “Are you kidding? How the f ** k balances three crackers and a stupid fig nutritionally?

“Give me that Big Brother. Three crackers and a f ** king fig? ‘

Despite the tiff happening just four short years ago, Megan captioned the video, “Damn, I used to be back!”

She added, “It’s official. I have tick tok! Good. It was only a matter of time. ONLY FUN PEOPLE ALLOWED. Follow me @meganmckenna #tiktok #meganmckenna ‘
