Their renewed connection led to marriage in 1988. The couple had one daughter together. After several years of separation, they finalized their divorce in 1994.

Marriage to Josh Brolin

In 2003, Lane became engaged to actor Josh Brolin and the two married in 2004. Later that year, an incident occurred in which Lane called the police during an argument, resulting in Brolin's arrest for domestic battery. Lane did not press charges, and Brolin publicly described the matter as a misunderstanding. The couple continued their marriage for several years, though their union was often described in media reports as troubled, with Brolin's struggles with alcohol playing a role in their dynamic.

Lane filed for divorce in 2013, citing irreconcilable differences. The couple had no children together. Although the specific terms of their divorce settlement were not publicly disclosed, Lane stated that she did not seek spousal or child support, and that they had discussed sharing financial assets amicably. Reports also indicated that Brolin entered a rehabilitation program in an effort to address his issues with alcohol around the time of their separation.
