Actress Mila Kunis, who is pregnant with her first child, reportedly wants to go for a second child soon.

The "Black Swan" star, who is preparing to give birth to a baby girl in "less than a month", is eager to have another child with fiance Ashton Kutcher next year, reports femalefirst.co.uk.

"She wants to get pregnant again right after this child is born, and she is cleared to do so by her doctor. She loved being pregnant and wants all of her children to be close in age," said a source.

"They both want a big family and have been telling everyone this," added the source.

The 30-year-old hopes to have a natural birth, but "Jobs" star Kutcher doesn't want to see her in pain.

"Mila was going to do an all-natural birth with no medications or sedatives, but she has been advised against this because she is such a small girl. Ashton will not accept this and refuses to see her in pain," said the source.

The source also added that Kutcher doesn't want his children to "become spoiled Hollywood kids. Do not expect to ever see them on any carpet".

The couple, who got engaged earlier this year, are planning to get married next summer.
