The Poseidon star is divorcing her husband Justin Siegel and has recently been spotted getting close to Counting Crows frontman Duritz.
And the singer reveals the pair has grown close after enjoying impromptu music sessions together.
Duritz says, "She can sing her a** off. But she toured with us onstage, so I knew how she could sing.
"I sing with her all the time. I actually think she sings better onstage with us... I like to make music with her."
