Schapelle Corby shares birthday joy by singing on Instagram

Schapelle Corby has been dreaming of celebrating a birthday back home on the Gold Coast for over a decade, and today on her 40th birthday she couldn't contain her joy.

The convicted drug smuggler shared a special selfie video with her over 200,000 Instagram followers.

In it she can be seen spinning around as she sings a little song, posted along with the caption "Mucking around on this sunny day".

The song is very short and goes like this:

I'm in Queensland;

And it's sunny;

And the palm trees;

Behind me.

The video has been watched almost 40,000 times since being posted earlier today.

In the post Corby tagged her friend @nat_zelz who responded to the song by writing, "I love love love this. Happy birthday beautiful."

To which the birthday girl responded, "Ahhhhh. Hi. I've been waiting for you. Hope I haven't destroyed your little song too badly."
