Can Kim Kardashian act?

Judge for yourself.

The Keeping Up With the Kardashians reality star, 29, guest stars on Monday's episode of CBS' CSI: NY.

In this exclusive clip (watch above), Kardashian (in stilettos, no less) marches into a detective's office in search of her boyfriend.

"Detective Flack? My name is Debbie Fallon. You're holding my boyfriend, Sam Baker," she says before handing the man a business card from her lawyer. "You are accusing an innocent man of murder."

Joining her in the episode: Vanessa Minnillo, 29.

The two play women tied to a murder scheme.

This isn't the first time they've teamed up: Both played cheerleaders in 2008's Disaster Movie.
