Christy Turlington says fear of flying after Sept. 11 led to her surprise bust-up with Hollywood hunk Ed Burns only weeks before they were to tie the knot.

The luscious supermodel blames Burns and his family and friends, who refused to board a plane to Europe after the terrorist attacks -- a reluctance which led to an irreparable rift. 

"No matter where we chose [to get married], some people would still have to travel, so if this was our reason for postponing, then we would have to wait until it was safe for everyone," Christy tells the October issue of Vogue

"Of course there was a possibility that such a time [might] never come." 

And it didn't, with Christy and Ed putting off their nuptials, then calling off their engagement altogether. 

Not that Christy doesn't take some of the blame for the busted betrothal, admitting she is a "true Capricornian control freak" who wanted to go ahead with the ceremony no matter what. And when she refused to relocate the event, that was that, Christy says. 

The leggy brunette, whose new book Living Yoga: Creating a Life Practice hits stands this month, also tells Vogue that yoga has changed her life -- and those of other celebs. 

"Madonna had an athletic body -- and yoga perfected it," she says.
