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

Megan recently had her followers in stitches with her TikTok debut which saw her recreating her iconic tantrums from her stint on Celebrity Big Brother.
She dressed up in a tracksuit, hoop earrings and a camo-print baseball cap, attempting to emulate her former wild-child self, as she mimed along to a recording of one of her diary room outbursts.
Mascara running, she ranted about the food she was being provided, which happened during her stay in the famous BB house during the 2016 season, which turned out to be one of the most iconic of all time, featuring the infamous David’s Dead mix-up.
She was seen throwing a hissy fit, having been asked to eat ‘crackers and figs’ while on rationing.
‘I can’t eat that s**t, what the f**k!’ she screeched.
The voice of Big Brother was then heard saying: ‘Megan, the meals Big Brother has been providing during the task have been nutritionally balanced.’
To which Megan replied: ‘Are you joking? How the f**k are three crackers and one stupid fig nutritionally balanced?
‘Answer me that Big Brother. Three crackers and a f**king fig?’
Despite the tiff only happening four short years ago, Megan captioned the video: ‘Damn I was cray back in the day!’
She added: ‘It’s official. I have tik tok! Well. It was only a matter of time. ONLY FUN PEOPLE ALLOWED PLEASE. Go follow me @meganmckenna #tiktok #meganmckenna’
