This will be the second marriage for Olivia who split from husband of eight years, Tao Ruspoli, in 2011. The Saturday Night Live star was also hitched once before to Pitch Perfect screenwriter Kay Cannon.
Olivia recently put her $2.5 million Los Angeles home on the market so she could reside permanently in New York with her funnyman beau!
