Tina Fey 'agonised over second pregnancy'

Tina Fey has confessed that she felt conflicted about whether or not to have more kids.

The 30 Rock creator and actress, who is already mother to 5-year-old daughter Alice, announced on Wednesday that she and husband Jeff Richards are expecting their second child together, a decision which she revealed was several years in the making.

"I went for my annual check-up and, tired of carrying this anxiety around, burst into tears the moment [the gynaecologist] said hello," she recalled in her new book Bossypants. "I laid it all out for her, and the main thing I took away from our conversation was the kind of simple observation that only an impartial third party can provide - 'Either way, everything will be fine'."

"I get up to go to the bathroom and study myself in the mirror. Do I look like someone who should be pregnant? I look good for 40, but I have the quaggy jawline and hollow cheeks of a mum, not a pregnant lady. It's now or never. This decision can't be delayed."

She went on to explain that she worried about how another pregnancy would affect her hectic career schedule, though she ultimately decided that family is more important than her professional life.

"What's so great about work anyway? Work won't visit you when you're old. Work won't drive you to get a mammogram and take you out after for soup," she wrote. "Hollywood be damned. I'll just be unemployable and labelled crazy in five years anyway."

Fey previously claimed that becoming a parent has made her "a more sympathetic human being".
