Janet Jackson makes a 'Big comeback'

Popstar Janet Jackson made a Big comeback, prompting some critics to suggest that the larger-than-life star needs to either go on a diet or invest in a new wardrobe – and go up a size.

The popstar (42) shocked fans with her heavyweight look on her 'Rock Witchu' Tour when she showed up on stage wearing a skin-tight yellow body suit that accentuated her curves in all the wrong places.

It was painful enough to see Janet trying to dance in her get-up, let alone imagine what it must have felt like to move in the tight suit.

If she doesn't go up a size, we might see another wardrobe malfunction on stage - but it won't be quite as sexy as the one she put on with Justin Timberlake during the Superbowl XXXVIII halftime show...
