Rumours that Britney Spears is pregnant have been stubbed out, literally, after she was photographed indulging on a cigarette.

The pop wreck has been the target of baby rumours after being snapped on numerous occasions with a round tummy.

However, the singer ended speculation after she was snapped puffing on a cigarette. She has also been enjoying vigorous sessions at her gym.

Spears has two sons with ex-husband Kevin Federline, Sean Preston, two, and Jayden James, one.
