London, Apr 2: Katy Perry is so determined not to get pregnant that she constantly chews birth control pills.

The singer says that she would love to start a family one-day, but is currently too busy focusing on her career to even contemplate about having kids.

"I love being in love, I love the idea of marriage and making babies - but not yet. Not until I''m 30,” the Sun quoted Perry, as telling Paper magazine.

"I basically chew my birth control tablets - I chew them like vitamin C, I''m like, ''nomnomnomnom,’ ” she added.

She added: "This is a really important time in my life. During the next two or three years, if I do things right, I will have a real career, and if I don''t, well, I''ll just be that girl who kissed a girl." (ANI)
