Actor couple Lee Bo-young and Ji Sung are finally tying the knot after dating for six years. They posted handwritten letters on their official online fan sites to announce the news on Friday.

The two met on the set of the 2004 SBS series "Save the Last Dance for Me," but their romantic relationship did not become public knowledge until paparazzi caught them together in 2007.

Rumors of a separation started to bubble up when the couple still showed no inclination to marry after dating for six years.

But they said they have been preparing for their wedding since March and will get married in Seoul on Sept. 27.
