Dead serious about shifting gears in her career, Disney star Hilary Duff continues venturing into more adult acting roles, which includes a guest stint on Law & Order: SVU.

The episode is entitled “Selfish” (which sounds like it could easily be the name of a dance track on the pop starlet’s latest album “Boy, why you so selfish?/Oh! Oh!/Super-selfish!/Oh! Oh!”) and will air April 28th.

Adding this to her budding resume of relatively risqué roles for the squeaky-clean tween, is her upcoming guest spot on Ghost Whisperer alongside her good buddy Jennifer Love Hewitt.
