Gigi Hadid is about to strut into motherhood.

The supermodel confirmed her pregnancy during a preview clip for Jimmy Fallon’s The Tonight Show at home edition episode, which will air Thursday night on NBC. She is expecting her first child with boyfriend Zayn Malik, a former member of One Direction.

“We are very excited and happy and grateful for everyone’s well wishes, and support,” she told Fallon during the 3 1/2 minute clip. She admitted her first craving so far has been bagels.

“We wish we could have announced it on our own terms but we are very excited and happy and grateful for everyone’s well wishes,” said Hadid, according to an advance excerpt of the video.

Hadid’s mother, Yolanda Hadid, told the Dutch outlet RTL Boulevard on Wednesday that her daughter is pregnant.

Yolanda Hadid said the baby is due in September.

Hadid’s mother said she is thrilled with the news of her daughter’s pregnancy and becoming a grandmother, or oma. She said she was surprised that the “little secret” was leaked to the press.

“I’m excited to become oma in September, especially after I lost my mom so recently,” she told the outlet. “But this is the beauty of life: One soul leaves us and a new one comes in. We feel very blessed.”

Yolanda Hadid’s mother, Ans van den Herik, died last summer at age 78.

Hadid, 25, and Malik, 27, have been dating off-and-on for several years. She has become one of the world’s most in-demand models and he was the first to leave One Direction to strike out as a solo artist.
