Robin Thicke's estranged wife Paula Patton has been tapped to testify as part of a court battle over the singer's pop anthem Blurred Lines.
The star and his collaborator, Pharrell Williams, are embroiled in a legal dispute over allegations they sampled music by Marvin Gaye in the 2013 chart smash.
The case is set to head to trial.
Court documents relating to the case have now revealed that Patton, who split from Thicke last year, has been asked to testify.
The actress has been listed as a witness, according to TMZ.com.
