The newlyweds are expecting their first child together, E! News reports.

Simpson, 30, and Ross — who were married on Aug. 31 — revealed in November that they were already trying to have a baby.

“We’re working on it,” Ross, 26, told E! News at the premiere of The Hunger Games: Mockingjay, Part 1. “I would like it. As many [kids] as possible!”

The couple recently spent thanksgiving splitting time between their two families.

“I do green bean casserole,” the expectant mother said about her holiday cooking. “I can do all the casseroles. I’m from Texas.”

This is Simpson’s second baby. She is mum to Bronx Mowgli, 6, with ex-husband Pete Wentz.
