Asked how she thought he would get on, Jools confessed: "I don't know. He's a funny little boy. I don't know, I really don't know. He really loves girls, he doesn't really like boys, as in playing with boys, and he's going to an all-boys school which is a bit worrying."
She added: "And he loves dressing up, he wears a dress every day, I'm not revealing anything, I just think he is the most different… I've never met a child like him."

"He is theatrical, interesting, totally like a little girl, and it's so funny because he and Buddy get on really well but Buddy is a real boy and he is like a little girl, but a boy so I don't know," continued the doting mum. "I have no idea. I just hope they have Frozen dresses in the dress up box, in an all-boys school. He is just a character."

"He is quite OK to leave me, and he is good with other people so we'll just see," she concluded. "I just don't know, it could go either way and I'm thinking: 'I am so worried,' I just really want him to enjoy it so I can relax.'"
