Keyshia Cole is currently on the road with Chrisette Michele and Mateo for her 'Woman to Woman' tour. At every concert, the R&B diva allows one fan to join her onstage for a duet of 'Woman to Woman.'

The ballad, which features Ashanti, is a confessional ode of two women being cheated on by the same man.

At Cole's Los Angeles show on Friday (April 19), the 'Heaven Sent' singer invited a young woman to perform the title song.

Cole opened the song up with her first verse but had to hold a finger up to shush the fan beside the fan who was singing along.

Eventually, the Oakland native allowed the women to sing -- or perhaps lip sync -- Ashanti's verse.

In the end, the two women sang in unison of the song's defiant lyrics. Afterward, Cole and the fan embrace in a loving moment of sisterhood.

Cole performed her last show of the 'Woman to Woman' tour tonight (April 21) in her hometown in Oakland, Calif.

The Grammy-nominated singer also just released her new single from the LP 'Woman to Woman' called 'Wonderland.' The cut features up-and-comer Elijah Blake.
