They said ‘I Do’ in front of just four people, Daniel's daughter Ella, 18, Rachel's four-year-old son Henry and two friends at a pal's house in New York.
A friend told Britain's News of the World: "Daniel and Rachel insisted on having a small, quiet wedding. They are madly in love and couldn't wait to be husband and wife - but they wanted minimum fuss. They had a couple of friends as witnesses and their children from previous relationships and that was it."
Rachel split from 'Black Swan' director Darren Aronofsky last year after nine years together. They never married but had a son together, Henry. They announced their split in November and by December Rachel and Daniel had got public with their romance.
While it sucks for Darren, she probably gave him great material for his next movie. Congrats to the happy couple.
