Pregnant Rumer Willis cradles her burgeoning baby bump in a fitted black dress trends now

Rumer Willis looked radiant as she attended the Year of Action Committee Launch Dinner in West Hollywood on Wednesday.

The daughter of Bruce Willis and Demi Moore, who hosted a baby shower earlier this month, announced the happy news that she was expecting her first child with boyfriend, Derek Richard Thomas, late last year.

Actress Rumer, 34, made a rare public appearance at the political action get-together which was held at Mediterranean restaurant Olivetta.

While posing for pictures at the event, Rumer cradled her bump in a fitted black dress that stretched over her stomach and featured a plunging neckline.

She added a long black cardigan to cover up and paired her look with black sandals.

The former Dancing With The Stars contestant tied her brunette hair into a bun as she posed for photos. 

In one snap, she is joined by Sophia Bush, who hosted the dinner in collaboration with Mejuri jewellery.

Rumer finished her look with a soft palette of make up and accessorised with a selection of silver jewellery.

Also making a stylish appearance at the event was Cara Santana, who looked sensational in a brown blazer and matching flared trousers.

She added a co-ordinating bralet underneath, flashing her chest and midriff.

The stunner accentuated her natural beauty with a gorgeous palette of make up including a soft smokey eye and tied her brunette locks into a slicked-back bun.

Rumer and her beau announced their pregnancy late last year in December in an adorable Instagram post that contained black and white snaps as Willis showed off her baby bump with Derek also in the pictures. 

In one photo, he gently rested his hand on her stomach while sending a shocked look towards the camera. In another, he placed a kiss on her growing bump.
