Shania Twain is planning a “big surprise” for her fans.

The country music star posted a video on her website, promising to reveal the “special gift” on her 44th birthday next week.

In the clip – which was shot in the garden of Shania’s home in Switzerland – the singer thanks fans for remembering her son Eja’s eighth birthday, before giving hints about the surprise.

Shania said: “Hi everyone, Shania here. First to start off, I want to thank you for all the beautiful birthday wishes for Eja’s birthday. Secondly, if you haven’t already seen on my website for August 28 on my birthday, I will be giving you a small gift of thanks for all of your support over the last year… You’ve been really wonderful, thank you so much.”

The “gift” is thought to be a “very personal travelogue” documenting Shania’s 2008 split from her husband, producer Robert ‘Mutt’ Lange, who reportedly had an affair with her best friend.

A source said: “It’s not new music, but it’s a piece that Shania put together of what she’s been doing for the last year. It’s definitely a totally new side of Shania that no one’s ever seen.”

Fans will also be able to watch Shania on TV later this month when she appears as a guest judge on ‘American Idol’.
