 Fact but you lost.

I have a pet dog.

True. I did enter a beauty contest because my family and friends encouraged me to, but you're right, I didn't win.

The winner won a contract to a top modelling agency. Modelling was never my dream anyway, so I didn't care. Being a model was my mother's dream. Not mine.

I have a pet dog.

 Fact

I used to own a pet kangaroo

 Fiction. Mine was also fiction.

I'm listening to Taylor Swift right now.

This game is a trap because I have to say whether you guessed right and then I have to post something new.  

Wrong, I did own a pet kangaroo. We shot it's mother on a hunting trip and kept the baby joey, but it ended up dying a couple of years later.

 Fiction.

When I was 19, about 2 years after I had moved out of home, I purposefully lit the house on fire one night that my family were living in, in the hope they would all burn to death.

 What was your kangaroo's name?

Mine was fact when I said it but now it's Rihanna.

I'll guess yours is fact.

I crashed a car and had my friend say he was driving.

We called the kangaroo 'Skippy'. We named him after a show that used to air here in Australia called "Skippy The Bush Kangaroo".

 Fact

My sister is almost 20 years younger than me.

 Fact.

Mine was a fact too.  Was you burning down the house fact?

I think Justin Bieber is cool.

You are correct. My sister is almost 20 years younger than me.

As for the burning down house statement... You were wrong. Though, I did want my family to burn to death, I didn't light the house on fire. The firefighters don't actually know what caused the fire. They speculated that a gas bottle may have exploded.

 I think Justin Bieber is cool.

 Fiction. I don't even think Justin Bieber's own fans think he's 'cool'.

I've illegally driven cars and motorcycles around town.

(illegally meaning the vehicles were either unregistered and/or I didn't have a licence to drive/ride them).

 Fact but who cares about the law unless you get caught?

I do think Justin Bieber is cool, because he says ignorant shit that makes people mad.  I secretly hope he's doing it intentionally.

I convinced a cop to let me out of a ticket by telling him the physics of the car made it impossible for me to stop at the sign.
