Alyson Hannigan is expecting second child with hubby Alexis Denisof

Alyson denied pregnancy rumors in September, explaining that she was simply too well fed. But now she took to Twitter to share the happy news with her followers.

“Yes, I am pregnant! This time it is NOT a food baby. We are beyond happy!” she wrote.

The 37-year-old actress and her husband Alexis Denisof, who have been married since 2003, already have daughter Satyana, 2½.

“Alyson is thrilled to be pregnant!” a source close to the star told Us Weekly. “She’s been wearing baggy clothes to cover the baby bump.”

And the news couldn’t have come at a better moment as Alyson’s character in the series How I Met Your Mother, Lily, is also pregnant.
