The reality TV star was not invited to the ceremony on Friday and said that she would have been kicked out if she was.
She told Now: "I'd love an invite to the wedding. But I'd probably get kicked out for trying to do the can-can in the middle of the dancefloor."
The 30-year-old, who is dating property developer Dan Foden, has her own reality TV show, Kerry Katona: The Next Chapter, on ITV2 but said that she wouldn't like to be in the public eye as much as Katie Price.
She added: "I wouldn't like to be in Kate's shoes. I feel pressure being Kerry Katona and I'm a nobody."
Katona is reportedly planning a musical comeback by featuring on a track with Basshunter.
