Anne Hathaway made her red-carpet debut as a mother-to-be at the Los Angeles Fine Art Show's 2016 Opening Wednesday evening, several weeks after she announced her pregnancy on Instagram.

The 33-year-old actress opted for a retro look, donning a loose-fitting black-and-white dress by Marc Jacobs. She accentuated her overall look with a swipe of pink lipstick and warm rose blush.

The star was hosting the event alongside her husband Adam Shulman, and the proceeds from the party would head straight to the St. Jude's Children's Hospital, a cause that's close to her heart, according to The Hollywood Reporter.

"It was a place that I had heard about but after I saw it firsthand, I knew that my life had changed and that I would do anything to help those kids and their families, and I would do anything to support this cause," Hathaway said in an interview with People.

It was reported back in November that Hathaway was expecting, and that she was already in the second trimester of her pregnancy. The couple had been seen out in Beverly Hills, and she was seen sporting a baby bump, as HNGN previously reported.

Hathaway will be gracing the big screens again this year, as she will star in "Alice Through the Looking Glass," the sequel to 2010's "Alice in Wonderland," which will hit theaters on May 27.
