Country pop singer Jessica Simpson, who has been appearing on reality shows rather than putting out records, made the announcement through her Twitter on Monday, saying, "It's true - I'm going to be a mummy!" The 32-year-old singer also posted a picture of herself dressed up as a "mummy" for Halloween, showing her baby bump. 　　This will be the first child for Simpson with her fiancé, former pro football player, Eric Johnson, whom she started dating in May 2010. 　　Johnson's divorce from his first wife was finalized a little over a year ago, while Simpson and Nick Lachey's marriage officially ended in 2006.
