Randy Jackson is leaving American Idol

"After 13 seasons, I felt now was the perfect time to leave 'American Idol',"

Randy Jackson is leaving 'American Idol' after 13 series.

The 58-year-old producer - who stepped down as a judge last year but returned for the current season as an in-house mentor - is "proud" of his stint on the programme but thinks the time is right to move on to something new.
