Serena Williams has made her very first red carpet appearance since accidentally announcing her pregnancy nearly two weeks ago.

The tennis pro, 35, attended the Met Gala in New York City on Monday evening in a gorgeous emerald green gown that highlighted her burgeoning baby bump and featured a plunging neckline.

Once inside the event, the athlete cut loose. She was seen in a Snapchat video dancing in front of sculptures and tapestries, even laying on a bench at one point.

The star confessed the Snapchat which revealed she was 20 weeks along was sent by mistake.

'I was on vacation, taking time for myself, and I have this thing where I've been checking my status and taking pictures every week to see how far along I'm going,' she said at Ted Talks in Vancouver last month.

She added: 'I've been just saving it, and you know how social media is – you press the wrong button and… My phone doesn't ring that much, and 30 minutes later, I'd missed four calls, and I'm like, "That's weird." And then I picked it up and I was like, "Oh no".'
