Ageing beauty Jennifer Aniston says she wouldn't ever have a baby via artificial insemination.

The actress, who plays singleton Kassie who decides to use a friend as a sperm donor to have a baby in new movie 'The Switch' would prefer to conceive a child in the traditional way, reports contactmusic.com.

When quizzed by talk show host Jay Leno on whether she would undergo artificial insemination, she replied: 'I'd wanna know the guy!'

Leno continued to tease the 41-year-old Hollywood star actress about the embarrassing subject matter putting her on the spot about how a sperm bank works.

'Well, you go to the bank and you have a card... I honestly don't know exactly,' she said.
