Call Bronx's Babysitter, CSI: NY Books Pete & Ashlee

Celeb couple to appear on the crime drama, playing Bonnie and Clyde-type villains in March episode

The list of celeb suspects stopping by the CSI franchise just keeps getting longer.

Most recently, we've heard all about Taylor Swift on the set of the Las Vegas-based original, and Sean Combs matching wits with David Caruso on CSI: Miami.

Now, new parents Ashlee Simpson-Wentz and Pete Wentz are slated to make an appearance on CSI: New York, CBS confirms to E! News.

The couple will leave baby Bronx Mowgli at home yet again to play Bonnie and Clyde-like villains. The episode airs March 18.

We just have to ask: Are the similarly omnipresent Heidi Montag and Spencer Pratt next?
