Destiny's Child reunites! Beyonce, Kelly Rowland celebrate Michelle Williams' new book. In her new book, "Checking In: How Getting Real About Depression Saved My Life -- and Can Save Yours," former Destiny's Child singer Michelle Williams says the phrase, "I need help" should be among the first lines of defense for anyone who's not feeling 100 percent. It's a lesson Michelle learned the hard way, by not taking advantage of it, when she was in Destiny's Child while struggling with depression, even though she was working alongside two of her best friends in the world. Now, Michelle's sharing a little peek at how she and Beyonce and Kelly Rowland have been checking in with each other to make sure that lack of communication doesn't happen again. "The only time we'll let y'all eavesdrop on our group chats!!" Michelle joked on Instagram on May 26, sharing three audio clips of her conversation with Bey and Kelly. "We're so proud of you, Mimi! You are so inspirational for both of us — and we just love watching you become exactly who you are and the world see your impact, wisdom and beautiful advice," Beyonce says at one point in one clip. Later, when Kelly asks Michelle what she hopes people will take away from her book, Michelle says, "It's OK to not be OK and it's OK to tell somebody you're not OK -- because I should've done that with y'all." Kelly agrees, telling her longtime friend, "People should know that along with friendships, there is humility and you have to allow yourself to hold a safe place in a safe space for all friendships to be able to check in ... When it's that person, your person, it's nothing that they'll judge you for, it's nothing you can't tell them. I think that's the greatest thing Destiny's Child has ever given me is my gift of friendship for you ladies." Beyonce chimes in, too, telling Michelle, "I just know Kelly and I feel so honored that we are now your safe space where you can express any and everything and we know that you are that for us and you've always been that for us, so we're just happy to be along this journey and happy witness the birth and your new chapter."
