Idina Menzel apparently finalised her divorce in secret last month.
The Frozen star married actor Taye Diggs in January 2003 and they have five-year-old son Walker Nathaniel together.
In 2013 they announced their separation, but papers were not immediately filed. However, TMZ now reports the pair secretly finalised proceedings on December 3 last year.
The website claims to have obtained court documents that show no action was taken until November 2014, when Taye filed the divorce petition in New York.
Taking their time may have allowed them to discuss issues such as child custody and the dividing of assets, as the divorce was finalised by the next month.
According to sources, the split has been amicable and the couple are dedicated to raising their son together.
It’s been a rocky start to 2015 for Idina, who was heavily criticised for her performance of Frozen’s Let It Go track on New Year’s Eve. During her stint on ABC show Dick Clark's New Year's Rockin' Eve, the 43-year-old received some comments that claimed she didn’t manage to hit all of the tricky song’s notes.
However, the star remained strong and took to Twitter to defend herself. She posted a picture of a quote she’d previously given during an interview.
"There are about three million notes in a two-and-a-half-hour musical; being a perfectionist, it took me a long time to realise that if I'm hitting 75 per cent of them, I'm succeeding,” it reads.
“Performing isn't only about the acrobatics and the high notes: it's staying in the moment, connecting with the audience in an authentic way, and making yourself real to them through the music.
“I am more than the notes I hit, and that's how I try to approach my life. You can't get it all right all the time, but you can try your best. If you've done that, all that's left is to accept your shortcomings and have the courage to try to overcome them."
When Frozen was released at the tail end of 2013, critics praised its sparky lead female characters. But there was a bigger hit lurking within: Let It Go, the Oscar-winning song that has become an LGBT anthem, inspired hundreds of YouTube parody covers and invaded living rooms the world over.
