The curvy starlet then took a self-inflicted Twitter hiatus in early July after she received a lot of "negativity" following her big news.
"Unfortunately with all the negativity people choose to send on twitter as well as threats to there own well being. I'm sad to say twitter is No longer for me. I have enjoyed all the kindness and love that came my way, as well as support. But this break is needed Life should be filled with positivity and holding each other up, not making threats and sending bad vibes. To those of you who made it a joy Thank you from the bottom of my heart," she said in a series of tweets.
But now she's back online (and has been since Aug. 6) and she's out, about and ready to bask in her pregnancy glow.
"Proud to join @Pampers today to celebrate Love, Sleep & Play!" she tweeted Wednesday as she was promoting an event in New York for the diaper brand where she showed off her baby bump when she arrived. She also debuted a shorter, darker hairstyle with blunt bangs.

Hewitt and Hallisay have also started picking out baby names even though they've decided not to learn their child's gender in advance
"They're not traditional, but they're not crazy," she told Us. " "They're sort of middle ground."
"I'm due in December and I don't know what I'm having. Meeting the baby is what I'm most excited about," she told People, adding that "learning to breastfeed" is what she's most terrified of.
Hopefully the new tot knows that his or her mom once joked that she should have those signature assets insured.
