The The One Man, Two Guvnors star and his bride wed in a private ceremony in front of 60 family members and close friends, reports The Sun.
The couple - Carey in a long-sleeved Monique Lhuillier gown named Catherine after the Duchess of Cambridge and Corden in a suit and black tie - then joined 220 guests in the grounds of former stately home Babington House in Somerset for the reception, which included champagne, a free bar and a wedding band.
David Walliams and his wife Lara Stone, Michael McIntyre, Jimmy Carr, Gavin & Stacey co-star Ruth Jones, Doctor Who's Matt Smith and singer Natalie Imbruglia were all pictured at the afternoon celebrations, which were said to have cost £200,000 in hiring fees alone.
The highlight of the day is reported to have been a spoof pop video organised by best man Ben Winston, the son of fertility expert Professor Robert Winston.
The two-minute clip recreated Corden's brief experience as part of a boyband named Insatiable and reunited the original members for a performance. Winston is also said to have persuaded Sir Paul McCartney, Robbie Williams, Gary Barlow, One Direction and Snow Patrol to play cameo roles, reciting lines from a song Corden had written as a teenager.
Corden and Carey had attended X Factor host Dermot O'Leary's wedding in Kent the previous day. 34-year-old Corden was seen arriving at the 18-acre country estate on Friday evening (September 14) by helicopter and on Saturday morning, he was spotted on a balcony at the venue wearing a customised West Ham shirt with 'Corden's Stag' on the back.
