The Duck Dynasty star will attend the event as a "special guest" of Rep. Vance McAllister, a Republican congressman in Robertson's home state of Louisiana.
"I am proud to have my close friend, constituent and small business owner, Willie Robertson, attend tonight's State of the Union Address as my special guest," McAllister said in a statement. "Willie is thankful for this opportunity and honored to attend. I look forward to the two of us representing the Fifth District in DC this evening and bringing some diversity to our nation's capitol."
Boss Hog previously starred in one of McAllister's campaign ads.
UPDATE: Robertson’s wife, Korie, will also attend, as per The New York Times. She is a guest of Sen. Lindsey Graham, a South Carolina Republican.
