Pregnant actress Jessica Alba denies reports she is to marry boyfriend Cash Warren - because she does not want her bump to show in a wedding dress. The 26-year-old was rumored to be engaged to Warren after the couple announced they are expecting their first child next summer. But a source close to the couple denies the reports, telling Usmagazine.com, "She doesn't want to be pregnant in a dress." Meanwhile, Alba's brother Josh tells the publication the family is looking forward to her having a baby, adding "We're all thrilled for them." Alba and Cash, 28, have been dating since meeting on the set of Fantastic Four in 2004. The couple reportedly split up earlier this year citing their hectic work schedules, but got back together soon after.
