The glamour girl held a relatively secret ceremony today [29.03.13) to tie the knot with the part-time stripper-and-actor but security guards were on site at the Rookery Manor hotel in South West, England to ensure their privacy.
The biggest hint the model gave to the nuptials was a tweet during the afternoon where she linked to a photo of a bow on her YouGossip account.
Accompanying the picture, she wrote: ''Tying the knot xxx''
Although Katie, 34, is yet to post confirmation of the marriage, The Sun newspaper reports the civil ceremony was a contrast to the couple's wedding in the Bahamas in January.
It is understood she was wearing a dress she bought locally, while the reception is believed to have followed a 'Willy Wonka' theme based on Roald Dahl's book 'Charlie and the Chocolate Factory'.
Earlier in the day, Katie gave another big clue when she referenced Billy Idol's 'White Wedding' song on Twitter.
She teased: ''as billy would say, it's a nice day for a . . . .
''great atmosphere with everyone an lovin the build up eeeeeek exciting xx (sic)''
