Did Scarlett Johansson just reveal what ended her marriage to Ryan Reynolds?

Though the 31-year-old actress doesn't mention her ex-husband of three years by name, she opened up in Cosmopolitan magazine's May issue about the "challenging" logistics of being with another actor.

"There has to be a real understanding of how you share your time, especially when two people's careers are going at the same rate," the Captain America: Civil War star said. "Or even if one person is more successful than the other, that also proves challenging. There may be a competitive thing."

The one-time couple split in 2011, and both have since remarried. Johansson said "I do" to Romain Dauriac in a secret ceremony in October 2014 and welcomed their daughter, Rose, one month later. Meanwhile, Reynolds tied the knot with Blake Lively in 2012 and they had their own daughter, James, in December 2014.

In the same interview, the Black Widow actress opened up about a relationship that made her hit "rock bottom."

"Long, long ago, I had someone in my life who was forever unavailable...but, like, so attractively unavailable," she said. "You have to get to your breaking point -- rock bottom is the moment when you're like, 'I've lost myself. Why am I standing outside this bar at 1:30 in the morning texting while my friends are inside? Or taking a taxi to see him at some ungodly hour? This isn't me.' That is the moment you've gotta cut it off. Otherwise, it will keep coming back, suck your blood."
