Alex Reid has warned Katie Price's new fiancé it is a ''rollercoaster'' being married to her.
The sexy TV star got engaged to part-time stripper Kieran Hayler over Christmas, just weeks after they began dating, and Katie's ex-husband Alex has advised her new lover she is one of the ''most high maintenance women in Britain'' and he should have gotten to know her better before popping the question.
Alex revealed to The Sun newspaper: ''They should take longer to get to know each other. It is a rollercoaster being married to her.
''Katie's in love with being in love. It's new and exciting and I hope a new deep love can form. As long as Kieran understands the world he's now part of, he'll be fine.''
The 37-year-old cage fighter - who was married to Katie for just 10 months in 2010 before they separated in January 2011 - admits being with Katie, 34, changed his life ''forever'', but he has warned hunky 25-year-old Kieran, who works as a part-time plasterer, the instant fame can be ''bumpy and rough''.
Alex - who recently endured a messy split from Chantelle Houghton - said: ''I wasn't well known but I became very well known. The second you open the doors to the public, your life changes and you can't close those doors straight away.
''It's great to start with, the ego is fantastic. But it becomes addictive. You have to realise there's more to life than having your name known.
''That stage isn't very comfortable. I certainly had some experiences, sometimes bumpy and rough, sometimes good.''
Katie's first marriage with singer Peter Andre - with whom she has two children, Junior, seven, and Princess Tiaamii, five - ended in 2009. She also has a son, Harvey, 12, with retired soccer player Dwight Yorke.
