Rosamund Pike, 35, is expecting her second child with her partner Robie Uniacke, whom she has been dating since 2009, her representative confirmed to E! News. The couple already have two-year-old son Solo together. Rosamund - whose engagement to director Joe Wright was called off a month before their wedding in 2008 - has always said she would like to become a mother and had planned to have more than one child. She said before Solo was born: ''As an only child, you've never known anything else. But I definitely know that I would like my child to have brothers or sisters.'' Meanwhile, Rosamund and Robie,
who also has four other children from previous relationships - currently have no plans to marry. However, the pair did decide to move in together following their first child's birth.
