British model Katie Price says she doesn't wear make-up now since she's too busy taking care of her children and sticks to using Vaseline to keep her lips moisturised.

The 36-year-old, who is now pregnant with her fifth child and has sons Harvey, 12, Junior, eight, and daughter Princess, six, from previous relationships, as well as nine-month-old baby Jett with her husband Kieran Hayler, lacks the time to apply cosmetics because she's busy with the children.

"The older you get, the less interested in make-up you are. A smoky eye is ageing and with four kids, the last thing on my mind is make-up,` she said.

"In fact, I don't wear any. Vaseline is the only thing in my make-up bag to keep my lips moisturised,` she added.
