After debuting her baby bump in eye-catching emerald at Monday's Met Gala, Serena Williams was back on the red carpet one night later to show off her burgeoning belly once again in an elegant maternity frock.

The tennis icon continued to make the A-list rounds on Tuesday evening as she stepped out to fete the launch of fashion house Burberry's DK88 bag at the brand's Soho boutique. Unlike her plunging gown from the night before, the expectant mother's navy blue Burberry pick was a slightly more subdued but equally stunning option for putting her baby bump on display.

Featuring a thigh-high slit that showed off the star athlete's toned gams and romantic lace detailing throughout, the mom-to-be's trench coat-inspired wrap dress called attention to Williams' athletic figure and her expectant bump with structured lapels and a bronze snakeskin-print belt which cinched at the waist.

Taking a more romantic beauty cue than her sleek strands from the night before, the glowing star wore her locks down in a wavy bob and opted for radiant, pink-hued makeup. A simple silver pendant and black pointy-toed stilettos were the perfect finishing touches to Serena's take on classic style with an edge.
