AITA for telling my husband he needs to help clean before guests come or I'm not hosting anymore?

My husband (34M) and I (32F) are hosting a dinner party this Saturday for 6 people. He invited his boss and coworkers—which is fine—but he expects me to handle everything. Shopping, cooking, cleaning, decorating. He hasn't lifted a finger.

Yesterday I asked him to vacuum the living room while I scrubbed the kitchen. He said "I'll do it later" and then spent 3 hours watching football. I reminded him again this morning and he sighed like I was asking him to do brain surgery.

I told him that if he doesn't step up and help clean before Saturday, I'm canceling the whole thing and he can explain to his boss why. He called me "controlling" and said I'm "making a big deal out of nothing."

Am I crazy here? I'm not his maid. I work full-time too. AITA?
