The couple are planning on walking down the aisle for the third time to reaffirm their commitment to one another after getting their relationship back on track since the 27-year-old hunk cheated on her with pals Jane Pountney and Chrissy Thomas last year while she was pregnant with their second child, Bunny.
A source revealed: ''Katie's ready to move on now.
''She feels that Kieran has worked through all of his issues and is now ready to let him back into her life.''
The 36-year-old former glamour model - who counts Peter Andre and Alex Reid among her previous spouses - originally married the former stripper on a beach in the Bahamas in 2013, and followed up the ceremony with a Willy Wonka-themed wedding two months later when they were back in the UK.
However, Katie - who, as well as Jett, 17 months, and six-month-old Bunny with Kieran, also has children Harvey, 12, Junior, nine, and Princess, seven, from previous relationships - is keen to forget about their previous weddings because all of the pictures feature her unfaithful friends.
A source told the Daily Mirror newspaper: ''She hates the fact that Jane is in all their original wedding pictures and wants to have another, big, fancy do that erases every memory of the friends that have crossed her.''
Nevertheless, the ex-pals may still make an appearance of some sort at the vow renewal as she previously said her two pet pigs - named after Jane and Chrissy - would be walking with her down the aisle.
She said: ''They will be the bridesmaids when me and Kieran renew our vows.''
