What if TT is John Travolta?

I've seen this about: http://www.celebrity-babies.com/2007/03/john_travolta_a.html

What if TT might have 'slow swimmers', maybe due to time-of-life (?), and Boyfriend decided to contribute, as they both want this child and it doesn't matter to them who's the biological father.

Now, what if the donor eggs came from some random donor, pre-chosen... but the resulting embryo(s) were implanted into the 'wife' of TT? Especially if the 'wife' of TT were of an age when her own eggs might not be as fertile as they used to be?

I know this sounds totally far-fetched, but what if all the parties know the score, and it's all been arranged that this child will have a special 'Uncle'/godfather who will be a very close part of this child's life?

Stranger things have happened and truth is stranger than fiction!
