The singer – who is Jessica Simpson's younger sister - is believed to be expecting her first child with new husband Evan Ross.
Multiple outlets in the US including People have confirmed the pregnancy but so far Ashlee and Evan have yet to comment.
If it's true, it will be a fantastic end to the year for Ashlee, 30, and Evan, 26, who've had a pretty incredible twelve months…
A Hawaiian proposal in January, beautiful Great Gatsy-themed engagement party in March, a stunning wedding at Evan's mum Diana Ross' estate in Connecticut in September… Oh, and Evan made his debut in the latest Hunger Games movie Mockingjay: Part 1.
Ashlee is already mum to six-year-old son Bronx Mowgli from her marriage to ex-husband Pete Wentz.
She's also aunt to sister Jessica's children: Maxwell, two, and Ace, one.
