If there's a sound that defines the early 2000s, Avril Lavigne's punky verve was definitely in the mix. (See hits such as "Complicated," "Sk8er Boi" and "I'm With You.") But what does a modern-day Lavigne have to share with us? We may soon find out.

On April 12, the Canadian singer/songwriter posted a photo holding a guitar while writing on social media, captioned, "Homestretch b****es." Though she didn't offer any other details, evidence points to the possibility that Lavigne's sixth studio album could soon be upon us.

Lavigne first started talking about a new album in 2017, but she told Billboard she wasn't necessarily in a hurry to finish it. The former Best New Artist nominee also suggested that she might return to her church and country roots, yielding a promise of an album that heads into uncharted territory.

"I challenged myself as a songwriter and I wanted to write about topics I hadn't hit on before," Lavigne said. "There's the love topic, but a lot of these songs are about life. I've experienced a lot over the past few years, and some of the songs just came to me."

Only time will tell what this "Girlfriend" has in store.
