4 of 261: Jessica Simpson and her fiance Eric Johnson welcomed their second child, a baby boy Sunday, June 30, 2013, a spokesperson for Simpson confirmed to OTRC.com. The couple has named their son Ace Knute Johnson. The middle name honors Johnson's Swedish grandfather, according to reports.

Simpson and Johnson are already parents to a daughter named Maxwell Drew, who was born in May 2012. Simpson confirmed her second pregnancy in Dec. 2012 by tweeting a photo of Maxwell Drew sitting on a patch of sand with the words 'BIG SIS' scrawled in it.

The singer and fashion mogul accidently revealed she was having a boy when she appeared on 'Jimmy Kimmel Live' in March.

'Oh my gosh, it's a total different pregnancy, I just feel awful - I've been vomiting,' Simpson explained to Kimmel. 'The crazy thing is, I never knew a wiener could make me nauseous,' she laughed.

'Well, I guess I just told the world that I'm having a boy,' she later added. 'I can't believe I just did that, that was not planned.'
