Michelle Williams claims she will never separate herself from her Destiny's Child bandmates.

The singer is working on her new album 'Journey To Freedom', which includes the single 'Say Yes', featuring Beyoncé Knowles and Kelly Rowland, with the three women appearing in the video for the track.

Michelle said: ''It's not going on a Destiny's Child album, it's going on my album featuring Beyoncé and Kelly, the same way Kelly featured us on her album. But no matter how much we try to separate ourselves when we're together, it is what it is - this is the group.''

'Journey To Freedom' is Michelle's fourth solo record, and it was always part of her plan to work with Beyoncé and Kelly on the project.

The trio also made a promise to continue teaming up on each other's solo projects, ''Whether that is appearing with Beyoncé from time to time on her tours, or on shows, or Kelly's album.''

She added: ''It feels wonderful [to work with them], and no matter how much we try to say it's not a Destiny's Child song [it doesn't matter].''

The reunion, which reportedly came together after Beyoncé and Kelly heard Michelle's single and loved it, was supposed to be kept a secret.

However, when the women went to shoot video for the song in a residential area and people started to gossip.

Michelle told the Hollywood Reporter: ''We filmed at somebody's house, and they probably got excited and called their cousins and friends and, next thing you know, the whole town was on one street.

''I woke up to the news of the song being leaked and I just hate when that happens because it was an unmastered version.''
