According to the site, the comedian proposed to the actress "shortly after the holidays." But as Radar readers know, sources told us in mid-December, before the holidays, that Jason and Olivia were secretly engaged and had already booked a wedding venue in the Saturday Night Live funnyman's hometown of Kansas City.
Jason and Olivia, who live together, have been a couple for more than a year. Both have been married before, with Jason getting divorced from actress and 30 Rock writer Kay Cannon in 2010 and Cowboys & Aliens star Olivia officially ending her union to Italian Prince Tao Ruspoli in 2011.
The pair have been spotted at University of Kansas basketball games, as Jason is an alumni of the school.
And now, as only Radar has reported, they'll soon be walking down the aisle in his hometown!
