Grillows is once again super real on the set of the two-hour CSI finale. 

Marg Helgenberger posted the above photo on her Instagram on Monday, writing, “I am crazy about this wonderful man!” adding the blue heart emoji of true, inter-castmate love. 

The actress also known as Catherine Willows has not been shy about sharing photos from behind the scenes of the highly anticipated special; last week, she posted yet another smiley photo of herself with Petersen, with the hashtags “Grillows” and “CSI4EVER.”

If only, Helgenberger. If only. 


The two-hour send-off is set to air Sept. 27 on CBS.
