Destiny's Child fans were undoubtedly super psyched when their favorite female trio reunited on Michelle Williams' new gospel track, 'Say Yes.' And now the 'Say Yes' songstress herself is speaking out about the bond that she and her former DC ladies share.

"I am so excited. It's one of my favorite songs on my album, and it's with my sisters," Williams gushed to PEOPLE about reuniting with Beyonce and Kelly Rowland on the tune. "And I can't believe it's been 15 years [since we've met]."

"That's why I was so happy when they did my album and Beyoncé had her braids! It took me back when I first met her and she had those blonde braids," she continued. "I was like, 'Oh my God, you're taking me back to 'Say My Name'!"

While Williams did get a little nostalgic, the three friends are also still very much in the present, supporting each other whenever (and wherever) they can.

"We're honored to be there for each other in our happy moments. I've never really had genuine female relationships until I met them. I don't care what anyone says, we miss each other," Williams explained. "We have that spiritual bond with each other where we know when you're really tired, you need your sister with you today or you just need a phone call to let them know you're thinking about them. I call them my soulmates."

While the trio are still just as close as ever, Williams takes notice that haters think she is less successful than her former Destiny's Child bandmates.

"A lot of things I do go under the radar, so people do feel that I'm not as successful as the other ones, but I've made Broadway history and my fourth album is coming out," she explained. "I've been working 15 years straight. I haven't stopped."

And as for the cruel comments that Williams endures from anonymous people online, she has a clear message:

"They are crazy! They're someone who takes time to Google me daily and dedicate their website to me," she said. "I try to ignore it. I've been able to say, 'Okay, my name is in your mouth. You're searching for me on Twitter. I don't even know you exist.'"

Preach it, girl!
