Katie and Kieran tied the knot on the beach in the Bahamas two years ago today (16 January) and they have marked the occasion with several cute new pictures for fans.
In one shot, shared on Katie's YouGossip site, the former glamour model is kissing Kieran while sitting next to him in the car. Katie has captioned the photo with the words: "Love love love."
The couple are smiling together in the second photo, and Katie has said: "It's our wedding anniversary today wooooo #soulmates."
But are they on their way to Elstree Studios in Hertforshire, where Celebrity Big Brother is filmed?
For the past few days, it has been widely rumoured that Katie is heading into the CBB house tonight, which could scupper any plans of a romantic meal for two.
Mum-of-five Katie is even said to have been offered a staggering £500,000 just to take part and CBB bosses have confirmed that someone new will be put into the mix tonight.
Will it be Katie?
Whether she walks up those famous stairs or not, it's great to see Katie and Kieran looking so happy after such a rocky second year of marriage.
Just 16 months after they said "I do", Katie announced on Twitter that she was to divorce her third husband after discovering he had been cheating on her with two of her friends.
This shock announcement came just days after Katie and Kieran unexpectedly discovered she was six months pregnant with their second child.
However, after packing Kieran off to a therapist for 'sex addiction' treatment, Katie decided to give her marriage another try - and they seem to be back on track.
The couple welcomed daughter Bunny into the world in August and they spent a happy Christmas together as a family.
