Los Angeles: Singer Zara Larsson says she always carries spare underclothes with her as she cannot repeat them another day as a habit."I always have an extra pair of underwear in my bag and if I don't, I would rather go without panties," Larsson told MTV Online, reports femalefirst.co.uk.Talking about her diet, the "So good" hitmaker has cut out cheese because she finds the thought of how the dairy product is made "weird"."I think cheese can be great, although I am trying to not eat cheese, because if you really think about what cheese really is, it's weird. It's the breast milk from a cow or a goat who is having a baby, it's weird," Larsson said.However, the vocalist has no problems with alcohol, and says she "always vandalises" the mini bar when she is staying in a hotel, although she has never made a call to an ex-boyfriend when intoxicated."I would never drunk dial an ex, because when I got a new phone, I looked up his number, I added it to my contact list just to block it," she said.
