Newly engaged and newly pregnant actress Jennifer Love Hewitt showed off her burgeoning baby bump on the red carpet of the Pampers Love, Sleep & Play campaign -- and revealed a new haircut to boot.

Hewitt arrived yesterday (Aug. 21) at the Vanderbilt Hall at Grand Central Terminal in New York City wearing a slinky black maternity dress, chunky wedges and brand-new dark, bang-heavy locks.

She also tweeted about the event, proving that despite quitting Twitter previously, she isn't ready to give up on social media all together.

Welcome back to the fold, Jennifer.
