Pregnant Rumer Willis goes topless under a sheer black robe in a stunning bumpsuit campaign

Rumer Willis left little to the imagination as she posed in the latest campaign for celebrity-loved bumpsuit pregnancy brand on Thursday.

The actress is photographed in stunning black and white, showing off her growing baby bump in multiple pieces from the line’s sleek loungewear line.

Rumer went topless under a black semi-sheer robe before laying on her side to model a white wrap top and underwear.

“Empowering women to embrace the beauty of motherhood is our mission and we’re thrilled to feature the stunning Rumer Willis in our latest campaign,” the brand said on Instagram.

Rumer promoted the campaign by sharing her favorite image on her Instagram story before going on a livestream with bumpsuit founder Nicole Trunfio.

The House Bunny star, 34, is expecting her first child with boyfriend Derek Richard Thomas.

She confirmed the pregnancy by sharing a photo of the 28-year-old kissing her stomach to Instagram in December.

Rumer and Derek went public with their romance last spring, and she recently admitted she’s “never been happier in my life.”

On Valentine’s Day, she thanked the hunk for “making me a mother and being my partner on this wild ride to parenthood.”

She said that he “takes such good care of me and our little one” and that they are “so lucky to love you.”

Rumer is the eldest child of actress Demi Moore, 60, and Die Hard star Bruce Willis, 67, who divorced in 2000 after 13 years of marriage.

She recently recreated her mother’s iconic Vanity Fair cover shoot, in which she posed nude while seven months pregnant with Rumer’s sister Scout, now 31.

For her version, Rumer opted for the same prone pose, but wore an off-the-shoulder sweater and a blanket around her waist.

The image was to promote her “capsule collection” for the NakedCashmere brand, which she said will have “the cosiest and most delicious treats”.

‘This is truly a dream come true and a long time in the making. I can’t wait to share with you all!’ Captioned Rumer, who credited her close friend Zoey Grossman with the photograph.

Since confirming her pregnancy, Rumer has had a blast curating her maternity looks while collaborating with her favorite brands.

In February, she was styled by her little sister, Scout, in collaboration with Free People.

‘@rumerwillis and I took over @freepeople and I (*FINALLY*) came to STYLE THE BUMP,’ commented Scout, who has 324,000 followers,’ commented Scout, who uploaded a clip of the fittings to Instagram.

All of Scout’s closet curations highlighted Rumer’s growing baby bump by sporting a crop top or unbuttoned blouse in every look.

As her due date nears, Rumer recently revealed that she has reached out to Demi and Bruce for parenting advice.

She told PEOPLE the duo, who divorced in 2000 after 11 years of marriage, let her know she will have “no control over anything” once her baby arrives.

Demi and Bruce also advised her to have plenty of grace with herself as she navigates this new and exciting chapter in her life.

She also took the time to praise her baby daddy Derek, who she says has been “an angel” throughout the pregnancy.

“He was so adorable and he’s just so excited to be a dad and we’re both so excited for whoever this little person is,” she gushed. “I couldn’t have asked for a better partner and he’s going to be such a great father.”

Rumer doesn’t yet know the gender of her little ones, but she can’t wait to meet them.

“I’m just so excited. I feel like sometimes I can just feel that kid’s energy and I can’t wait to hear them laugh, find out who they are, play with them and get to know them,” the screen star continued.
