The Russian owner of Chelsea football club, Roman Abramovich, is the richest person in the UK with £7.2bn.
He's spent a lot of that money at Chelsea, spending £140m to buy the club and then another £133m on getting loads of top players at Stamford Bridge.
A Sunday newspaper came up with the list of the UK's richest 300 people.
The paper reckons that Jack and Kelly Osbourne are the UK's richest teens, just in front of Charlotte Church and scooter seller Dominic McVey.
