Halle Berry joined Twitter and Instagram - and her first post is topless

Halle Berry has joined Twitter and Instagram.

The 49-year-old actress certainly made a grand entrance when she signed up to the social networking sites on Tuesday by posting a topless shot for all to see.

Taking to her new accounts, the brunette beauty uploaded the elegant photo, which sees her walking through a picturesque forest with no clothes on, alongside the caption: "Hi everyone. Welcome! Today is a very exciting day for me... I'm looking forward to sharing our world through images that reflect my emotions and perceptions.

"I am in awe of photography and its ability to capture and reflect this extraordinary world that we live in.

"I'm excited to share with you my love of nature, the arts, fashion and much more in the hopes that the images will inspire, promote conversation and bring you joy. (sic)"
