Singer Michelle Williams has revealed that Beyoncé and Kelly Rowland are as close to her as sisters and she loves the relationship they have with each other. 

The Destiny's Child bandmates teamed up for Williams' new single 'Say Yes' and recently got together to shoot a music video for the track. 

Speaking to People magazine, Williams described the other girls as her 'soulmates' and confessed that they are the strongest women in her life: "We're honoured 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."

She went onto add that there's a 'spiritual' connection between them and that she has the utmost respect for their friendship: "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."
