Vanessa Hudgens reveals her pregnancy on the red carpet.

The actress Vanessa Hudgens, one of the hosts of ABC’s Oscars pre-show, included a subtle pregnancy announcement in her coverage of the red carpet on Sunday evening.

“I clearly have a lot to be excited for,” she said at the beginning of the broadcast, positioning her hands on her stomach.

Ms. Hudgens, 35, wore a fitted black Vera Wang gown with long sleeves and a turtleneck. She did not explicitly discuss her pregnancy during the broadcast, instead keeping her attention on the stars she was interviewing.

A representative for Ms. Hudgens did not immediately respond to a request for comment on Sunday.

This is the third consecutive year that Ms. Hudgens, who became a household name with her role in “High School Musical” in 2006, has hosted “The Oscars Red Carpet Show” on ABC.

Ms. Hudgens married Cole Tucker, a baseball player, in Mexico in December. (For that occasion, she also wore a streamlined Vera Wang gown.) This will be the couple’s first child.

During the broadcast, Ms. Hudgens traded off interviews with her co-host, Julianne Hough, and acknowledged that the ceremony was taking place on Indigenous land. Her interview subjects included Emma Stone, Simu Liu, Ariana Grande and America Ferrera.

When her coverage shift concluded, she held a microphone in one bejeweled hand and beamed into the camera. “That was a lot of fun,” she said.
