Following the duet, Smirnov told Jamelia that she is "so beautiful," while the British star added that as soon as she rehearsed the track with the contestant, she thought he was "fantastic".
Jamelia's last single in the UK was 'No More', which charted at number 43 in 2007. The song followed a string of Top 10 hits including 'Superstar', 'Thank You' and 'See it in a Boy's Eyes'.
The UK performer will return to a role in reality television later this year, after landing a spot on The Voice in Ireland.
