The Walk the Line star has been the subject of several baby rumours dating back to 2010 and each one has subsequently turned out to be false.
But American magazine UsWeekly is reporting the actress and her husband Jim Toth are now expecting their first child. Quoting ""multiple sources"", editors at the publication suggest Witherspoon is 12 weeks pregnant.
The couple wed at Witherspoon's ranch in Ojai, California in March last year (11), just a year after they started dating. The actress has two children by her first husband, Ryan Phillippe.
