According to English website the Sunday Mirror, Lily Allen and husband Sam Cooper are expecting a baby brother or sister for little Ethel. Lily, 25, is said to have had her three month scan already, everything was well. Sam, 34, and Lily's second baby reportedly is due in December, around the same time of Ethel's first birthday. A source told the Sunday Mirror, "Lily has started telling her friends and everybody in her close circle is so excited for her. It was a surprise, but Lily and Sam are thrilled. The pair of them have loved every minute of parenthood so far and wanted to expand their brood quickly. So it's great timing." Another friend said, "They are great parents and absolutely devoted to Ethel. The pair of them are just delighted they've got another one on the way. They're such a happy family with Ethel. This is really great news."

The couple revealed that they were expecting again on their wedding day in June, 2011. Baby Ethel was born in December. The couple had previously suffered a tragic miscarriage at six months. In 2008 Lily also suffered a miscarriage, whilst dating Chemical Brothers' Ed Simons.
