On 40th birthday, Chelsea Handler poses topless

Comedian Chelsea Handler celebrated her 40th birthday by posing topless and by showing off her medical marijuana card.

Handler turned 40 Wednesday and to celebrate the occasion, her friend Whitney Cummings shared a photograph of the two of them together, reports aceshowbiz.com.

In the photograph, Handler is seen topless with her bosom pushed against Cummings' face.

"Happy birthday to the always elegant @chelseahandler. This is 40," Cummings captioned the image.

A day before her birthday, Handler herself tweeted a photograph of her new Medical Marijuana ID.

"I'm a legal marijuaner. Just in time for my 40th bday tomorrow. Now I just need to get a lighter," she wrote along with an image of the card.

Handler has been an outspoken advocate of the drug. She once filmed a video with rapper Snoop Dogg which showed them smoking and eating dog treats called Dogg Food. Besides, she is no stranger to baring her assets for the camera.
