(CBS SF) – Academy Award-winner Halle Berry just signed up for social media. Making her inaugural entrance into Twitter and Instagram on Tuesday, the 49-year-old actress went with a sexy “au naturel look” by posing topless with her back to the camera.

The former “Extant” actress describes the reason why she dove-in to the social media world on her first Instagram. “I am in awe of photography and its ability to capture and reflect this extraordinary world that we live in.” Berry says.

Berry has over to 85,000 Instagram followers and close to 10,000 Twitter followers since Tuesday afternoon, and is following Prince, Adele and NASA. Yes, NASA. (Get the “Extant” connection?) On both her bio sections on Twitter and Instagram, she quotes Henry David Thoreau “It’s not what you look at that matters, it’s what you see.”
