Jennifer Love Hewitt will 'wait' for wedding

Jennifer Love Hewitt has returned to Twitter!

The star, who quit in July soon after announcing her pregnancy because of all the "negativity," is back on for a cause. She wrote on Wednesday, "Proud to join @Pampers today to celebrate Love, Sleep & Play!"

She stepped out in New York, proudly showing off her bump, sporting new bangs and with less makeup than we're used to seeing, at the Pampers "Love, Sleep & Play" launch event at Grand Central Terminal.

Hewitt, 34, is engaged and expecting a baby with her Client List co-star Brian Hallisay.

She tells People they'll wait until the baby arrives to think about a wedding.

"I'm not putting that on myself also! We're going to wait," she says. "I'm going to get down and be cute again, and then we'll be ready to go."

The couple will also wait to find out the sex of the baby. "I don't know what I'm having. [I'm due] in December. Everybody's really excited. Meeting the baby is what I'm most excited about," she says.

What do you think of her maternity look?
