Alyson HanniganAlyson Hannigan has revealed she’s given up being vegan while pregnant - and is craving ginger ale.

The former Buffy star, who now appears in US sitcom How I Met Your Mother, is currently around six months pregnant with her first child and she told Us Weekly this week: “I basically went from being a vegan to… now it’s meat and cheese — and ginger ale!

“Ginger ale, I love. Apparently, my mom craved ginger ale when she was pregnant with me! Maybe it’s a hereditary thing.

“But, yeah, I didn’t eat any meat or cheese before - now I have to.”

She added that the producers of How I Met Your Mother have decided against writing her pregnancy into the show: “It had been discussed whether or not they would write it in, and they had the opportunity to, but just working with babies for one week confirmed it’s a good thing they’re not writing it in. Babies are hard to work with!”
