Lily and David have been inseparable ever since they were first linked this autumn and are happier than ever.   

The star separated from husband Sam Cooper in 2015 after four years marriage. The former couple announced they finalized their divorce in 2018.  

They share joint custody of their two children: daughters Ethel, seven, and Marnie, six.

The Newsroom actor famously dated Save The Last Dance star Julia Stiles between 2011 and 2015, and was in a relationship with former fiancee Maria Thayer from 2009 to 2011.
