The 37-year-old actor, who has been in a relationship with McNelis for over a decade, quipped he keeps their relationship strong by making sure their home was "immaculate" before he headed off to Toronto for the International Film Festival, reported People magazine.
"I try to keep the romance on the reg. I've been with my girlfriend 11 years, and as anyone knows, it's been a long- term, fully monogamous relationship that requires work, a lot of work.
"Before I came away to TIFF I ended up staying until five in the morning because I decided I was going to clean the entire house. I've done all the grocery shopping, all of the laundry, stuff that we just share and both do all the time. I thought it'd be nice for her to come home to everything immaculate and done. I put flowers in the bedroom and in the kitchen, so she came home and was happy," Hunnam said.
