The 42-year-old actress and her long-term partner Ryan Reynolds only welcomed their daughter Esmeralda into the world 19 months ago but it seems they're wasting no time adding to their brood as they're said to be expecting again.

The brunette beauty - who is known for keeping details on her private life secret from the public - is said to be in her second trimester, according to E! News.

The couple, who met on 'The Place Beyond the Pines' in 2011, have opened up slightly on life with a little one but are yet to share a photograph of little Esmeralda.

Ryan, 35, said recently: "My biggest investment is my family. I'm with the person I'm supposed to be with - I'm not looking for anything else beyond Eva - and I feel very lucky that we have a beautiful, healthy daughter, who is an angel."

Meanwhile, although Eva knows roughly what to expect second time round, the 'Hitch' star admitted during her first pregnancy that she was relying on baby forums to help prepare her for the birth of her little girl.

She said at the time: "I try not to Google too many things because it is frightening, but I do go to babycenter.com and read the comment sections from other mothers because I find so much solace in that. Just knowing that I'm not alone out there and that other moms have gone through the same thing can at least get me through the night."
