Chrissy Teigen shared the very first glimpse at her baby bump on Sunday, posting a photo to Instagram less than a week after announcing that she and husband John Legend are expecting their first child.

The 29-year-old model seemed surprised by her fast growing belly, captioning the bathroom mirror selfie, "Somebody is early to the party."

Following her excited post, haters took to Twitter and shamed the star, suggesting that she looked like she's having twins.

"Good thing I am unoffendable or this would be a rough few months," she tweeted.

She may be a little "offendable," however, sending a few of her haters sighing emoji faces. Others, however, got direct responses. Clearly getting annoyed, Teigen reiterated that she wasn't having twins and asked people to "please stop," explaining that she "didn't announce at a week."

"Get out of my uterus!" she declared to her dissenting Twitter followers.

After receiving so much hate, Teigen revealed that she was already done sharing her pregnancy on social media.

"No more preg tweeting for me, lesson learned!! Back to food and reality TV and hay things," she wrote.

Nonetheless, these are exciting times for Teigen and Legend, who have been very vocal about their struggles with trying to get pregnant. They even referred to their issues when making their pregnancy announcement on Oct. 12.

"John and I are so happy to announce that we are pregnant :)," she wrote on Instagram. "As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family."

Since her big reveal, Teigen has been keeping busy. She attended the La Mer's Celebration of an Icon 50th anniversary party on Wednesday and even celebrated Halloween with Legend and a few of their friends, including Jessica Alba and her husband Cash Warren, at Los Angeles' haunted hayride in Griffith Park on Saturday.
