AceShowbiz - Beyonce Knowles has teased she's been "cooking some music" during a group chat with her Destiny's Child bandmates Kelly Rowland and Michelle Williams (II).

Michelle took to Instagram to share audio recordings of several conversations she'd had with Beyonce and Kelly about the release of her book "Checking In: How Getting Real about Depression Saved My Life - and Can Save Yours".

In one of the chats, the girls talked about what they were up to, with Kelly saying she was making a soup, while Bey revealed she'd been working on her music. "I'm cooking some music," she laughed. "That's Chef Boyardee and Chef Boy-Kelly."

Later in the chat, Beyonce praised Michelle for opening up so fully for her new book, in which she discusses her battle with anxiety and her mental health.

"You are so inspirational for both of us and we just love watching you become exactly who you are and the world sees your impact and wisdom and your beautiful advice and your discernment. We're just so proud of you," the "Single Ladies" star gushed.

On Michelle's part, the 41-year-old told Bey and Kelly, "It's OK to not be OK, and it is OK to tell somebody you're not OK. ... I should have done that with y'all." She elaborated, "I've been open about a lot of things, but I never was really truthful about how I really was."

"Even though y'all have proven to be safe friends, safe sisters, sometimes people have to know you're not going to be looked at differently if you say, 'Y'all, I've been really sad a little too long. Something's going on,' " she continued.
