Actress Anne Hathaway has flaunted her growing baby bump, with a photograph on social media.

In the Instagram image, the 33-year-old is seen standing on a beach in a red two-piece bikini. She's seen holding her baby bump while smiling at the camera, reports aceshowbiz.com.

"Happy 2016 to my beautiful Instafriends! So, posting a bikini pic is a little out of character for me, but just now while I was at the beach I noticed I was being photographed," she wrote alongside the image.

Hathaway, who is really happy about her pregnancy, continued: "I figure if this kind of photo is going to be out in the world it should at least be an image that makes me happy (and be one that was taken with my consent. And with a filter :)."

At the end of the caption, the actress, who tied the knot with Adam Shulman in 2012, wrote: "Wishing you love, light and blessings for the year ahead! Annie."

Her pregnancy was first confirmed in November last year.
