Celebrity baby names: Maxwell
The news was announced on the singer's official website with a message from Jessica and husband Eric Johnson reading: 'We are so grateful for the love, support and prayers we have received. This has been the greatest experience of our lives!!'
Maxwell is Eric's middle name and his grandmother's surname, while the choice of middle name was inspired by maternal grandmother Tina Simpson, whose maiden name is Drew.
The pair later welcomed a son, Ace Knute, in June 2013.
