I believe part of what you say maybe true.. I think she is desperate to have a baby to kind of get over the one she lost with Pete just before they split..I think she never got over that loss ( not the right wording I know but can't put it any other way)
I also don't believe Pete is over her either.. ..
She's obsessed with babies and weddings because they equal media attention. But even that is drying up. No-one cares about Thickie Price and her latest convenient penis/wedding/pregnancy. It's the same old, same old. When you've seen one of KP's convenient penises/weddings/pregnancies, you've seen them all.
