The 37-year-old said he can only be tied down to one person for short periods, reported Contactmusic.
"Probably, eventually, for a short period of time. Do you mind group weddings? If it's like a Mormon wedding with me marrying 15 women and a couple of men, just for balance, and if you're not averse to that, it could happen. Or it could be just two of us but for a very short period of time," he said.
"The future Mrs Brand? Well, if she's from the future I want her to have a jet bike, X-ray vision and fire lasers out of her finger tips. I don't know, I'm just looking for the same things as everyone else, someone who's kind and sweet and ready to be swept into a whirlwind of insanity," he added.
