And to mark their special anniversary, the reality TV lovebirds shared cute messages to each other on Twitter.
In a break from filming in Marbella, Georgia shared a picture of them one year ago in Ibiza with the message: "Our first picture in Ibiza... No one thought it would last past Ibiza... Only we knew it would... We knew from day one...
"The year we have had has been unreal... So lucky to experience everything in life with you, my best friend. Happy one year @tommy_mallet I love you so much."
Awwww, we feel emosh!
Meanwhile, Tommy also shared his love for his gorgeous girlfriend on Twitter, accompanied with a message to the haters who didn't believe they would last.
On Saturday (26 September), he wrote: "A year on and still as passionate as ever about each other!! Love my girl to bits... WHO SAID IT WOULDN'T LAST THOOO."
He added: "Big up everyone who said it wouldn't work!! Happy one year."
Fans responded with messages of support, with one saying: "Gorgeous couple! My favourite in #TOWIE I love how you always have each others back that's what keeps you solid x."
Another said: "It's nice to see 2 people so happy, so booooooo to the haters. #welljel. Cheers to another year xx."
Georgia and Tommy are currently filming The Only Way Is Marbs.
Earlier this week, the loved-up pair headed to the beach and re-enacted scenes from Baywatch in their red swimsuits.
Last series, we saw Tommy declare his love for Georgia, presenting her with a promise ring.
After giving it to her, he told Georgia: "I wanted to get you something to show as much as we are together, I am planning on staying with you forever. This isn't a little relationship like everyone else's is.
"We know we are going to get married. This ring is just to show in the meantime, before we are engaged, that it's a promise we will be together forever."
TOWIE returns to ITVBe on Sunday 4 October.
