Sharon Osbourne forgot the name of one of Hollywood's most famous songs
Not content with just forgetting the names of her acts, X Factor judge Sharon Osbourne has now ceased to remember one of film's most famous songs.
The 64-year-old was criticised earlier in the competition after asking fellow judge Louis Walsh "what's her name?" when introducing Saara Aalto as the "songbird from abroad".
Saara, who is in Sharon's over-25s category, was set to be singing Titanic track My Heart Will Go On on Saturday night's show.
However, the X Factor judge again had to ask Louis for assistance as she struggled to introduce the track.
She said: "We are about to hear one of the themes from one of the biggest movies in movie history - the Titanic song.
"I don't know what the song is called but it's Saara Alto."
Viewers were not impressed with Sharon's latest gaffe.
Following Sharon's last mistake, concern grew over whether she had been drinking ahead of the show.
However, the judge told Good Morning Britain back in October that she was "thinking about something else. I wish I could come up with a better excuse".
She added: "I was thinking about songs, and I wondered... what are we going to do next week and then I'm like, oh she's in the bottom two again, and all of this is going on in my head and then they go 'it's you, it's you' and I'm like 'what? What am I doing?'
"It's just me, I'm just a bit dotty. But drinking? No."
Sharon responded to the comments about alcohol by saying: "Listen you trolls on Twitter! I have seen too many careers destroyed, family members destroyed from alcohol, this Mrs ain't going there."
