Mitt Romney's sons are set to appear on "Conan" this Wednesday, according to the show's website.

The sons of the presumptive GOP presidential nominee -- Tagg, Matt, Josh, Ben and Craig -- are scheduled to all appear during the first guest spot on Conan O'Brien's TBS talk show.

As Bill Carter of The New York Times notes, this will be the first time that a Romney family member has appeared as a guest on a late night talk show during this election cycle. Gov. Romney previously appeared on David Letterman's show to perform a Top Ten List.

Lorne Michaels invited Romney to appear on "Saturday Night Live" last season, but Romney was unable to fit the show in his schedule.

Romney's sons have increasingly hit the campaign trail as surrogates for their father. Last weekend, a video was released by the campaign highlighting home movies of the Romneys in honor of Father's Day.

The upcoming "Conan" appearance should go better than an appearance in Arizona last week, when Josh Romney was heckled by Ron Paul supporters.

The Romney sons will appear alongside actor Rob Corddry and the band Shinedown. It will air at 11 p.m. EST.
