Lott, 20, has been dating the model for the past two years and said that his busy schedule does not allow him to accompany her on tours, reported Contactmusic.
"My boyfriend, Oliver, is a model and often just as busy as me, so mum still comes along when I travel. It's no fun being in a hotel on your own - I get lonely," Lott said.
"She looks after my scheduling because I'm rubbish at that. She's also honest and tells me straight if I'm doing something wrong. She always has my best interests at heart," she added.
