The hit ITVBe show posted a video to Twitter of key moments from the show’s history including when Lauren Goodger pushed ex Mark Wright into a swimming pool.
Other hilarious parts include Sam Faiers asking for a vajazzle and Gemma Collins telling people to ‘Google her’.
TOWIE tweeted: ‘SHUT UP! 10 years of #TOWIE!? BRAND NEW episodes coming this September, starting with an anniversary speciall.

The video starts off by zooming in on a satellite view of the world as it pans in on a ‘welcome to Essex’ sign.
It then sees Sam, 29, asking Amy Childs, 30, for a vajazzle with Harry Derbidge, she says: ‘Have you heard of the vajazzle, can you do me one?’

A source told the publication: ‘It’s a shame as Mark has clearly forgotten his roots. The show made him who he is and he wouldn’t have had all of his work gigs, like his radio show, without TOWIE putting him on the map.
‘He’s said he’s in a different part of his life now and doesn’t want to go back to Towie again.’
The source added that ITV ‘aren’t losing any sleep’ however as they’ve managed to secure ‘the real king of Essex, Joey, for the upcoming special.
MailOnline contacted Mark’s representatives and ITV for a comment.
