London, June 18 : Starlets Keira Knightley and Sienna Miller have confessed that holding a baby for their film 'The Edge Of Love' triggered their maternal instincts and left them feeling broody.
The film, based on the love life of Welsh poet Dylan Thomas, sees the two actresses playing characters that have young children.
And carrying the youngsters around left Sienna feeling broody.
"As a woman you have instincts and you do get a bit broody, definitely," The Daily Express quoted Sienna, as saying.
However, the 26-year-old, who has reportedly split from her own Welsh love, actor Rhys Ifans, added hastily, "It didn't last, though."
On the other hand, her co-star Keira gushed about the babies, saying: "The babies were amazing, absolutely gorgeous."
