Well I've just heard from a friend, who heard from her boyfriend, who heard from reliable source that is the Daily Star (so it must be true!! ) that Alex wants an annulment as he felt pressured into the wedding. He was rushed to Vegas and married off, his family weren't there and the whole thing was orchestrated by Jordan's management.
Of course, this comes from the mouth of the Daily Star so I dare say it's completely made up but you never know eh!
