Olivia Wilde has taken her romance with Jason Sudeikis to the next level. The 28-year-old Butter actress - who plays a stripper called Brooke in the satirical comedy movie - has moved in with her comedian actor boyfriend of nine months.

"They are living together now," and are "totally inseparable," a source told Us Weekly.

The blissfully happy couple are said to be joined at the hip but are in no rush to wed, as they have both been married before. Saturday Night Live star Jason was previously married to actress and 30 Rock writer Kay Cannon from 2004 to 2010. Olivia divorced her husband of eight years Italian American filmmaker and musician Tao Ruspoli in September 2011.

"They've both been married, so they've already experienced that and know what it entails. It's something for down the road," the source added.
