I think they started "dating" before the 显示 even aired. I think they hit it right off the bat and then afterwards it got 更多 serious. While filming house of wax (I dunno what time that was during oth) he proposed so what was that 04, 或者 05. I dunno but they got married in 05. And divorced a few months after. So something like that
It was probably about 2 years (maybe a couple of months more). They met on the set of the 显示 and the 显示 was first filmed in 2003 (premiered in Sept but probably started filming around June 或者 July) and they got married in April 2005. So they definitely dated for less than 2 years and then they were only married for 5 months. I know they started dating during the filming of the first season... but that could have been late 2003, early 2004. So I think it's 安全 to assume it was about 2 years that they were together (dating and married)-- maybe closer to 2 1/2 years.
