You Used Your First Ever Tweet To Say THIS?

In honour of Twitter's 8th birthday, we're looking back at celebrities' introductory posts - and some of them aren't so pretty.

Do you remember what you wrote for your very first tweet? If you're like us, you probably have no idea - but you can easily find out.

In honour of Twitter's 8th birthday, they've launched a tool that lets you download your first tweet. Like looking back at your old school pictures, reliving your first tweet can make you feel nostalgic - or a bit embarrassed.

You can also download the first tweets of your favourite celebrities. And while some of them are cute and clever, others are aren't so pretty. But, hey, the first time is meant to be awkward, right?
