Legendary songbird Mariah Carey performed her cover of Foreigner’s ‘I Want To Know What Love Is’ on ‘GMTV’ today. The singer’s album has just beendropped in the UK, two months after it’s release in the US.

Great performance! Mariah certainly has stepped up her game this year with the vocals after generally horrendous showings in 2008. It’s endearing to see her deliver powerful vocals like these with such consistency, especially given the number of interviews and press junkets that she’s had to handle while promoting her album, movie and fragrance. Hopefully her hard work translates into better sales in the UK than the dismal reception she received in the US.

Update {Sam}: Interview after the jump…

What do you think of the performance?
