Devo co-founder Gerald Casale is denying he had a 9/11-themed wedding, calling photos of it "a set up."

“Deep apologies for all offended. There is a real explanation and it’s not what you think. Surprise cake and pix to TMZ was a set up. TBC…” Casale tweeted.

The "Whip It" performer and his bride, Krista Napp, were photographed celebraing their union on the 14th anniversary of the World Trade Towers last Friday. According to pictures obtained by TMZ, the couple chose a wedding cake resembling the fallen towers with their faces on the top of the cakes, and handed out personalized box cutters to guests as parting gifts.

TMZ said it spoke to guest at the couple’s reception who said others guests were not upset by the controversial theme, and vouched for the groom saying he has a “real heart as an artist, and is a super sweet guy.”

FOX411 reached out to Casale but did not receive comment.
