Bomer, who was also seen in the one-night-only, star-studded reading of Dustin Lance Black's 8, would play the older brother of Blaine Anderson, played on the series by How to Succeed… star Darren Criss.
The stage and screen actor is in talks to guest star on an April episode of "Glee," in which he will sing alongside his onscreen sibling, Criss.
Bomer, best known for his work on USA Network’s "White Collar," has also been seen in "All My Children," "Guiding Light," "North Shore" and "The Texas Chainsaw Massacre: The Beginning," among others.
"Glee" airs Tuesday nights on Fox at 8 PM ET.
