Sharon Osbourne denies claims she's not coping with The X Factor

After some fairly bizarre behaviour

Sharon Osbourne's X Factor behaviour has been a leeetle bit controversial thus far.

She became quite literally our favourite person IN THE WORLD (apart from disguise-sporting, milk-drinking, north London-party-house-buying Justin Bieber) after appearing to be absolutely wasted during the first X Factor live show.

If you didn't watch it, she kind of put us in mind of someone inappropriately drunk at a low-key family gathering – in a good way.

And on Sunday's show, she managed to forget the actual name of her actual act, Saara Aalto (after previously forgetting what country she was from).

Shazza, are you OK hun?

Some people have claimed she's not coping with the pressure of the show and that she's mentally exhausted.

A source said: "She's in an incredibly vulnerable state of mind. Everyone is concerned.

"She moved house and now is working two jobs - one in the UK and one in the US. She's pushing herself to the limit," they told The Sun.

But a rep for Sharon has dismissed reports, blaming "long flights" (between her two jobs at The Talk in LA and The X Factor in London) for her behaviour.

Which sounds very fair – there is a SEVEN HOUR TIME DIFFERENCE.

We would DIE.

She spoke about name-gate on Good Morning Britain earlier this week.

Piers Morgan asked her what we're all thinking: "Have you got a clue what is going on in this show" to which she responded: "Behave, you know what it is, I'm terrible with names."

"Maybe if I had of had a drink I'd be better with people's names, I should try drinking."

When (attempting) to introduce Saara on Sunday, Sharon said: OK everybody, now is the songbird from abroad" before her face turned to pure horror of the kind you see on people when they've just been informed of some terrible thing they did when really drunk.

She then muttered to Louis: "what's her name?" and he said: "SAARA!"

It was all a bit uncomfortable.
