The 23-year-old actress will be making a big jump and marrying Reynolds whom she has been dating for almost one year.
According to FemaleFirst, the couple will be announcing a wedding date in the near future. A source revealed, "We can expect an engagement announcement from Ryan and Scarlett any day now. They are very much in love and have decided to take the next step. Scarlett is thrilled!"
The couple confirmed that they were an item last April, just after Reynolds announced his separation from Canadian singer, Alanis Morissette. Before hooking up with Reynolds, Johansson dated her co-star from Black Dahlia, Josh Hartnett, for nearly two years.
