"They both think it would be so great to be expecting together,” a friend says. "They keep on talking about how it would be awesome to go through it all together."
The new additions would join Jessica's two kids with husband Eric Johnson — daughter Maxwell, 4, and three-year-old son Ace. Ashlee is mom to seven-year-old son Bronx with ex Pete Wentz, and 13-month-old daughter Jagger Snow with husband Evan Ross.
However, they might have to convince their hubbies to go along with the plan.
