Jessica Simpson has given birth to a baby boy.
The US singer and actress and her fiance Eric Johnson welcomed son Ace Knute Johnson on Sunday, Us Weekly reports.
Ace, who was born in Los Angeles via scheduled C-section, is a little brother for the couple's one-year-old daughter Maxwell Drew.
Jessica's spokesperson said: "Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great. Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."
Ace's middle name honours 33-year-old dad Eric's Swedish paternal grandfather, Knute Johnson.
Jessica, 32, announced her pregnancy in December and in March she let slip that she was expecting a boy.
The star revealed on Jimmy Kimmel Live! that she hadn't been feeling well during her second pregnancy, adding: "I never knew a wiener could actually make me nauseous".
She followed up by saying she "couldn't believe" she "just told the world" she was having a boy.
