Vanessa Kirby

Vanessa Kirby was the talk of the town at a panel event for the aptly-named The Fantastic Four: First Steps in Mexico City in May.

Draped in a glitzy metallic Schiaparelli gown, the actress gently cradled her bump, flanked by co-stars Pedro Pascal, Joseph Quinn and Ebon Moss-Bachrach.

She and fiancé Paul Rabil have since welcomed their bundle of joy, with Rabil sharing the news via Instagram in October. 

Rihanna

The Met Gala carpet was abuzz this year, as pop goddess Rihanna debuted her look for “Superfine: Tailoring Black Style” with one very conspicuous accessory.

Partner A$AP Rocky confirmed the pregnancy news in an interview with Associated Press journalists on the red carpet.

“It’s time to show the people that we was cooking up. I’m glad everybody’s happy for us because we’re definitely happy, you know!” he gushed.

Rihanna showcased an absolute masterclass in tailored couture, sporting custom Marc Jacobs for the occasion.

Stepping out for AFL’s biggest night cloaked in head-to-toe periwinkle silk, with a sheer shawl overlay, Tiffany looked iridescent in custom Viktoria Woods as she cradled her most notable adornment.

“Brownlow with an extra plus one,” the mum-to-be captioned her Instagram post from the night.

Michelle Dockery

Michelle Dockery, 43, made a stunning red carpet reveal as she stepped out for the much-anticipated conclusion of the long-running Downton Abbey franchise, Downton Abbey: The Grand Finale in September.

The actress wore floor-length cornflower-blue Prada featuring an off-shoulder, crystal embellished strap, and a bump-accentuating bodice that burst forth into a flared skirt.

Dockery was joined on the red carpet by her husband, Jasper Waller-Bridge, the brother of Fleabag star Phoebe Waller-Bridge.
