Former Neon Jungle singer Jessica Plummer is set to be a first-time mom.

The 23-year-old and her longtime beau Jaz are preparing for parenthood and Jessica took to Twitter on Saturday (25Jun16) to reveal the news.

She posted a photo in which she is showing off her growing belly in a selfie, and later tweeted her gratitude for her followers' well wishes.

"THANK YOU honestly means the world," she wrote. "Jaz and I are over the moon. Couldn't be happier to be starting a family with my childhood sweetheart."

The baby news comes nearly a year after she and her fellow bandmates, Shereen Cutkelvin, Asami Zdrenka, and Amira McCarthy decided to call it quits last July (15).

Months after their split, Jessica lined up a high-profile acting gig in romantic comedy How To Talk to Girls at Parties. The John Cameron Mitchell-directed film stars Nicole Kidman, Elle Fanning, Ruth Wilson and Matt Lucas, among others.
