The Atomic Kitten and Big Reunion star tied the knot with childhood friend George at a ceremony held near Bristol on Sunday, 14 September.
A blissfully happy Kerry returned to Twitter this afternoon with a simple message: "Happiest girl alive!! Xxxxxxx."
She added this morning: "Love waking up with my husband @mrgsjkay really want to rewind and do it all again.. Really was the best day EVER xxxx."
Kerry and ex-rugby league player George became engaged in Blackpool in April 2013. They actually knew each other as teenagers in Warrington - and George jokingly proposed way back then! - but true romance only blossomed in later life.
So far, details of their wedding ceremony have been kept under wraps but it's believed Kerry's close friend Katie Price was a bridesmaid.
Another bridesmaid was Danielle Brown, the sister of former Spice Girl Mel B, who tweeted: "Thankyou for asking me to be bridesmaid @KerryKatona7 @mrgsjkay loved every minute of it maybe a little too much at the end lol love yas."
Other celebrities in attendance included Kerry's Atomic Kitten bandmates and her former Big Reunion co-stars Scott Robinson and Jimmy Constable.
It was a pretty eventful day for one guest, Atomic Kitten's Natasha Hamilton, who was taken to hospital at the end of the night after going into suspected labour. The heavily pregnant singer was kept in hospital for 48 hours until her contractions stopped and she was released home for now.
It's been reported Kerry was walked down the aisle by her only son, Max, while eldest daughters Molly, Lily-Sue and Heidi were bridesmaids. All four are Kerry's children from previous relationships.
Kerry and George's four-month-old daughter Dylan-Jorge was obviously a bit too young for that honour!
