Denise Van Outen has penned a play about heartbreak and will be touring it around the UK with herself in the lead role.

The Chicago star tweeted that she had been co-writing the play, called Some Girl I Used To Know, for most of this year and let her followers know the website address.

She wrote: "For the best part of this year I've been co writing a play about love & heartbreak. I want to share it with you. somegirlIusedtoknow.com."

Denise then followed with another tweet: "This one comes from my heart 'Some Girl I Used To Know'."

She also posted a promotional photo from her shoot for the play, showing herself lying on a bed with a lap top and wearing lingerie.

The play follows Denise as Stephanie Canworth, a successful celebrity who is married but starts to look back over her past when an ex contacts her through Facebook.

Denise split from husband Lee Mead in July and last week went on holiday to Dubai with Joss Stone, where they met Prince Harry for a charity dinner.

Her new play will tour the UK from January to March next year.
