The young actors announced they were divorcing after just five months of marriage last month, but will continue to play Brooke Davis and Lucas Scott, who had a brief romance in season one.
Bush explains, "My job is my job, and my personal life is my personal life, and I keep them separate.
"It's not always easy, but it's my work--it's what I love and take pride in, and I won't let that slack because of personal circumstances."
