Jessica Simpson wants to get married after her baby is born.

The singer - who has had to cancel her wedding plans twice due to surprise baby news - hopes to walk up the aisle with her fiancé Eric Johnson as soon as possible after the couple's second child arrives.

A source told Us Weekly magazine: ''[Jessica] was telling friends she wanted to get married a few months after the baby is born.''

The insider claims Jessica was joking during her baby shower on April 14, ''Let's have this wedding already before I get pregnant with another one!'''

The 32-year-old blonde already has 12-month-old daughter Maxwell with Eric, and the pair were surprised to discover she was expecting another child - a boy, due to arrive in July - so soon after.

Jessica - who got engaged in 2010 - is very body conscious, especially due to her new role as the face of Weight Watchers US, so has employed a personal chef to ensure her diet is as healthy as possible during her second pregnancy.

A second source said: ''The chef is there all day. Jessica eats things like egg whites and sausage. It's healthier.''

Jessica and her family have recently moved into Ozzy and Sharon Osbourne's former Hidden Hills house in California, which they snapped up for the sum of $11.5 million.
