Everytime I hear this song, it cracks me up. Known as one of the founding members of Destiny's Child (before they had all those changes), Letoya is enjoying her solo career. This tune is from her second 2009 solo album entitled Lady Love. And for those breakups that ended on a sour note, life is about karma -- and seeing your ex when you're feeling good and looking damn fly (hair and outfit so right). He must regret the day that he left you... Check out Letoya's video "Regret" here.
