Is Rihanna heading for a Britney Spears style meltdown?

The star’s Tweeted pics of herself hooked up to a hospital drip

Is Rihanna crying out for attention?

Last night, Rihanna Tweeted a disturbing photo of herself hooked up to a hospital drip just hours after allegedly ‘necking champagne' at the Met Ball - and all without a word of explanation to her worried fans. (US sources have since reported she's been treated for exhaustion.)

So what's really going on with Rihanna?

I know she's always been kinda ‘out there', but I'm actually starting to worry - to the point where I wouldn't be surprised if we found out tomorrow that she'd nipped down to her local salon and sheered all her hair off in true bald-Britney fashion.

It just seems as though everything the super-talented star does right now is for attention.

There's the see-through sweaters, the ever-changing hair colour, and the persistent posting of controversial pics without any explanation.

Like that one three weeks ago, which showed her ‘cutting up' a white powdered substance on top of a man's head at LA music festival Coachella.

I get that celebs want to push boundaries and make statements - Lady Gaga does it so well, standing up for minority communities whose voices often go unheard.

But what's Rihanna's motivation? On her Twitter account she simply says: 'I'm crazy and I don't pretend to be anything else.'

Fair enough, I guess. But she's a role model to millions of impressionable young fans...

And I'm a huge fan, too! So the last thing I want is for her to go all Li-Lo on us. Because when that happens it's a tough road to recovery.

Let's face it, Britney's never really made it back - and we're still tentatively waiting for a verdict on the outcome of Lindsay Lohan's career revival.

So rest-up and look after yourself, Rihanna. We don't want to lose you - you're too talented for that.

Do you think Rihanna's crying out for attention?
