Ashlee Simpson is reportedly expecting her first child with Evan Ross.
The couple, who got married in August, are set to welcome a baby into the world next year, according to E! News.
The 30-year-old singer already has six-year-old son Bronx with ex-husband Pete Wentz.
The 'Hunger Games' star Evan, 26, recently admitted he wants to have as many children as possible with the blonde beauty.
Speaking last month, he said: "I would love to [have kids]. As many as possible."
Asked about married life, he added: "It's the best thing ever.
"I've been with her now for a while so it just feels right. I'm happy to say she's my wife."
Ashlee was said to be equally keen to give a sibling to Bronx, and sources close to the couple - who married in a romantic ceremony held at Evan's mother Diana Ross' lavish home in Greenwich, Connecticut - previously said they "can't wait" to see their families grow.
The insider said: "They can't wait [to have a child together]."
Bronx already has some experience of being a big brother, as Pete also has three-month-old son, Saint Lazslo Wentz, with girlfriend Meagan Camper.
The Fall Out Boy rocker split from Ashlee in 2011 after three years of marriage.
