People magazine suggests that the 31-year-old star does not want to cause herself any undue stress whilst she is expecting, and so has temporarily called off her planned 2011 wedding to former NFL player Eric Johnson, 32.
The couple were originally intending to tie the knot this month, in what would have been singer Jessica's second set of nuptials, having had a short lived marriage to Nick Lachey between 2002 and 2006.
People magazine quote a source close to the couple - who have been engaged since November 2010 - as saying: 'They're both still really committed to getting married, and were both really into making decisions about what kind of wedding they wanted.'
'It's just going to be at a later date now [because] they really want to enjoy this time in their lives.'
Did you delay your wedding because of pregnancy? Or did the blue line make you want to hot foot it up the aisle even faster?
