Nagra was dating Irish actor Kieran Creggan who she moved to South London with. They first met on the set of Fair Ladies at a Game of Poem Cards.
Before dating the photographer, she was questioned on her plans for marriage:
"Not yet. My theory right now is that if it ain't broke...! I'm not going to leave it too long, but not just yet. There are a few things that I still want to do. And it's so much hassle trying to plan a wedding [laughs]. I just want it to be perfect." (2007)- IMDB
The pair were together for seven years before they tied the knot. Her ER co-stars Scott Grimes and John Stamos performed at the ceremony and her former ER co-star Maura Tierney officiated the ceremony.
They had their first son on 19 th May 2009; Kai David Singh, however less than a year later Nagra filed for divorce on 8 th February 2012.
