The new baby is Ashlee’s second child.

She previously welcomed a boy, Bronx Mowgli, six, with her former husband and Fall Out Boy bassist Pete Wentz. The couple then divorced in 2011.

In 2013, the songstress began dating Ross, son of soul legend Diana Ross. By 2014, the couple were married and this is their first child together.

Ashlee Simpson's sugar bag is oh so sweet

Congratulations Ash!

The last time we saw Ashlee, she was just hours away from giving birth, and even in the 11th hour of pregnancy, she still managed to look fashionable and stylish!

On a recent excursion the blonde beauty was spotten in a black midi dress and comfy flip flops. She topped off her look with a trench coat and a Lanvin studded bag.

This isn't the first time we've seen the 7th Heaven star with the high fashion carryall and we can see why. The chain strap, quilted detail, and gold hardware ticks a lot of the trends that are hot right now. Not to mention the classic shape and black color that goes with everything.

The Sugar bag is available at Neiman Marcus for $2500. If that's too much of an investment, switch to a tote from the carousel below. These stylish picks can be worn all year long and will transition from the office to cocktail hour seamlessly so don't hesitate to pick one up today.

On Monday, they were spotted as they stepped out for lunch in Los Angeles.

Ashlee wore a black maxi dress and a chic trench coat. With her baby bump blossoming, the loving couple walked arm-in-arm and even shared a kiss.

Also on Monday’s outing, the duo stopped by a baby nursery to pick up some supplies for their new addition.

Ashlee’s actor/singer hubbie was also spotted preparing for the baby girl last week as he stopped by Beverly Hills’ high-end baby supply store Bel Bambini.

The ATL actor picked up a baby mattress while his wife stayed home.

And acquiring the necessary supplies isn’t the only way that Ross has been preparing; he’s also taken to Instagram recently with a slew of anticipatory photos, mainly from the couple’s 2014 wedding.
