Sibling rivalry is not something new to ears nor is the fact that all of us with siblings have cried or made our brothers or sisters cry with delight or post a fight. But Rosemarie Dewitt did not do that. She just helped her director make another co star cry on the sets for a scene .

Rosemarie Dewitt is playing sister to Emily Blunt in the movie 'Your Sister's Sister' directed by Lynn Shelton. The movie also co stars Mark Duplass. Unlike some of her previous outings where she has played a sane sister to siblings on the wrong track, this time around she is the one out of her mind. During a certain scene Emily Blunt was supposed to cry. To get a genuine reaction Dewitt embarassed Emily by asking her how she felt when Chris asked her to shave her pubic hair? Oops! That is embarassing for sure. Emily laughed loud with tears coming out and the shot was captured. 

Rosie sure got it right for the director and the movie. She's also got it right in her personal life. She is married to actor Ron Livingston since 2009. They both met on the sets of Standoff drama series and hit it off. Her man has worked in some good projects both on TV and big screen. His work include Indie 'Holly' and TV series 'Sex and the City'. They both seem to be doing good at the moment.
