Scarlett Johansson's Divorce: Grandma Reacts To Rumors

Scarlett Johansson dished to David Letterman Monday about her grandmother's reaction to rumors about her divorce from Ryan Reynolds.

Reports alleged that Johansson ended the marriage because Reynolds was pressuring her to have children, which "couldn't be further from the truth," she said.

"She called me on my phone and was like, 'That bastard, you should never have children for anybody baby, you take your time. You got your career on the line,'" Johansson said.

Johansson and Ryan Reynolds split in 2010 after two years of marriage.

The actress recently told Cosmopolitan magazine that their hectic work schedules prompted the split.

"Relationships are complicated.. and being married is a living, breathing process. I think I was not fully aware of the peaks and the valleys. I wasn't prepared to hunker down and do the work," she said in the magazine's January issue. "Both of us were extremely busy. We spent so much time apart. It's very difficult. It's bad."
