Sharon Osbourne hasn't forgotten Saara Aalto's name since she made a live show gaffe on 'The X Factor' two weeks ago.

The 64-year-old judge had a mind blank two weeks in a row last month when she couldn't remember her act's name when she was asked to introduce her for the sing-off but, despite the slip-up, the Finnish singer thinks her mentor is so "sweet."

Speaking exclusively to BANG Showbiz, she said: "Sharon is so sweet and she always remembers my name."

The 29-year-old beauty has proved a huge hit with viewers thanks to her angelic vocals but she has admitted she's no idea who will win the show after Gifty Louise was given the axe last week after losing the sing-off against Four of Diamonds.

She explained: "I didn't see that coming, I really thought she [Gifty] could be in the final, so I was like 'Oh my god, she's left.' I think in this competition everyone is very good and very different so I don't know who can win, I think we all have our own fan base and very different fan bases actually."

Since the live shows kicked off last month, fellow contestant Honey G - who is a wannabe rapper - has hit the headlines as viewers believed she was a "fake" and a novelty act.

But, when asked about the controversial rapper, who is also in the over 25s category, Saara said: "I shared my room with Honey G for the first week in the competition and she was like that, I really think she is real and I like her a lot."
