This girl is an amazing singer, we've watched all her videos but this has to be the best!

We reckon Olivia Thai is going to be big... she's already huge on youtube with loads of hits but it's not just her amazing voice but her backing, erm, dancers that make us laugh and keep us watching!

How does she keep a straight face while her brother, cousin AND her dog are prancing around behind her? If she can stay that calm we reckon she's got a good chance in front of Simon Cowell and the X Factor judges!

Check out the end of the video when her cousin says 'hey, be gentle!' hehe

We prefer her cover of Chris Brown's With It more than the original version! What do you think, has she got a glittering career ahead of her?
