With the shocking revelations coming out in Prince Harry's book Spare, I want to know what the biggest bust-up you've ever had with a sibling is and is it worse than the one between Will and Harry?

My sister is 17 months younger than me so you can imagine how much we fought. I once bumped into my sister in the middle of the town that we lived in and she was wearing my t-shirt. I made her remove it there and then and go home in her bra.

Mine's quite violent, but the worst thing I ever did was push my sister down a flight of stairs in the house And she breathed one of her ribs, but in return Like she did push me off the top of a bunk bed and I landed head first onto some plates So you win some glue some

I'm on team, I don't give a fuck.
