Only now is she interested in Junior. She would barely look at him when he was a baby/small child.
Anyone remember that reality episode when Jnr had been in Cyprus for a week or two with his grandparents and Peter flew out to collect him. When they got home, Katie had gone to bed. Didn't bother waiting up to see the baby she hadn't seen for weeks. When Peter called her out on it, she just shrugged and said she was tired after working.
Wild horses wouldn't have stopped most mothers from seeing their child in those circumstances.
Not to mention the time (now removed from archives, hopefully by Peter who didn't want Jnr to ever see it) she was filmed saying, "Give me a girl next time Pete and I might bond with it." I remember it very clearly because it was so shocking.
