The two singing superstars have been an item for two years now and the Biebs says that Gomez is so affectionate towards him that it makes him love her even more.
"I'm attracted to someone who's a good listener, who is there for me and who pays attention to what I am saying. Also, I'm very affectionate so need someone affectionate like me," the "As Long As You Love Me" crooner said in a recent interview with Top of the Pops magazine.
While being a good listener and affectionate surely are good reasons to love someone, Bieber says that Gomez's physical beauty and funny nature makes his task even easier.
"She's hot. Of course, every guy likes their girl to be hot, which Selena is. But I like to mess around and pull jokes, so I like to be around people who make me laugh and share my sense of humour. That's Selena for sure. She is a really great person and I think she has one of the best smiles in the world," he added.
