She raised eyebrows with her antics on Teen Mom 2, but Jenelle Evans has sparked outrage after revealing that she hasn't stopped puffing on cigarettes - despite the fact she's currently breastfeeding her 2-mont-old son, Kaiser (nicknamed Kai).

The 22-year-old tweeted an image of her boyfriend Nathan Griffith, Kai’s father, passed out on a chair— but what many noticed, instead, was the pack of cigarettes on the floor.

The Teen Mom 2 star later confirmed that she hasn’t been able to kick the habit, tweeting: “I’m outside right now smoking a cig lol”

However, when attacked by Twitter users over her confession, she added: "Nobody smokes in my house. We step out on the front or back porch."

Despite Jenelle's claims that she only smokes outside, however, plenty of people slammed her for smoking at all, pointing out that it is not in the best interest of the infant she’s breastfeeding.

The NHS website reveals: "If you smoke while breastfeeding, your baby will be exposed to nicotine through your breast milk.

"If you or your partner smoke, never share the sofa or bed with your baby."

However they do add: "But breastfeeding will still protect your baby from infections and provide nutrients that they can’t get from infant formula. So don't stop breastfeeding if you're finding it hard to quit smoking. You can use nicotine replacement therapy (NRT) while breastfeeding."

Do you think it's fair for a mother to smoke while breastfeeding?
