Benoist, 28, reportedly cited "irreconcilable differences" in the court documents, and doesn't want either party to have spousal support. She just wants to change her legal name back to Melissa Benoist.
Benoist and Jenner got engaged in 2013 and were reportedly married in March 2015, so the marriage lasted less than two years. They had no children.
Jenner won "The Glee Project" in 2012 and played Ryder Lynn on "Glee" from 2012-2015. Benoist played Marley Rose on "Glee" from 2012-2014. Jenner guest starred in two episodes of "Supergirl" earlier this year, and was recently in the movie "The Edge of Seventeen."
"I love working with him," Benoist told People in March 2016. "We only have fun working together. He's my person to act with. He's my favorite scene partner, always."
Why did they split? A source told Us Weekly, "The distance was an issue, things weren't working. It's amicable and mutual." It's also too bad, but distance is often an issue in Hollywood relationships, when couples film apart for long periods of time.
"Supergirl" Season 2 returns to The CW on January 16, 2017.
