Evan Rachel Wood and Zach Villa have parted ways.

The "Westworld" actress and her fiancé decided to pull the plug on their relationship and end their engagement. According to The Blast, Wood, 30, and Villa broke up a month ago but are only now officially announcing their breakup.

The "Thirteen" star may have also confirmed that she has split with Villa on her birthday. On Thursday, Sept. 7, Wood turned 30, and in a tweet, she wrote: "All the single ladies!"

Back in January, the ex-couple was spotted wearing silver bands on their left ring fingers on the 2017 Screen Actors Guild Awards red carpet. Later that night, Wood was overheard introducing Villa as her fiancé to "Mr. Robot" star Rami Malek, People reported.

Wood and Villa first met in 2015 when they performed together in a John Hughes-themed cabaret in Los Angeles. The two then decided to team up and form the electro-pop duo, Rebel and a Basketcase.

Wood's ex-fiancé is an actor trained at Juilliard. Villa is also a "self-taught multi-instrumentalist and singer-songwriter who plays guitar, bass, keyboards and drums, among other instruments," according to the band's bio.

Meanwhile, it seems that Wood has decided to focus her energy and attention on work as she is busy with filming the second season of "Westworld" these days. In fact, the actress has been sharing photos and videos from the set of the HBO series on social media. Earlier this month, she shared a clip of herself sneaking off the set of "Westworld" while wearing her Dolores wig.

Prior to being engaged to Villa, Wood was married to actor Jamie Bell, with whom she shares a 4-year-old son. Earlier this year, Wood opened up about her child and her sexuality when she received the Human Rights Campaign's Visibility Award in Charlotte, North Carolina.

"There was a time, despite what it may have looked like on the surface, that the fear had gripped me so tight, and I felt broken and unlovable," Wood said of being a bisexual. "And I did not think I would see tomorrow. But because of the voices I listened to, because of the people I identified with, the films I had watched, the music I had heard, because of words like 'bisexual' and the doors that it opened, I'm still here — and I didn't miss out on the most beautiful thing I've seen yet, and that was my son."
