Shanghaiist is not one to visit the many, various, countless, plentiful, and numerous gossip sites on the internet and saved in our bookmark folder. However, after an accidental click or two while innocently surfing the internet at work, we stumbled upon several interesting reports claiming that Christina might be performing at her upcoming Shanghai concert with a "noticeable bump". Could Christina have a bun in the oven? The speculation has the celebrity gossip blogs in a kerfuffle.

With Christina keeping mum and the gossip sites and newspapers sticking to their claims, the jury is still out about the status of the married soul singer's uterus. Those who care can judge from the recent pictures of Christina here or here.

All of the rumors didn't stop Christina from performing at a recent stop on her Asian tour in Osaka, Japan, last Monday (pictured). Judge for yourself: baby or tight belt?
