A renowned music manager has dealt Lindsay Lohan's younger sister Ali a devastating career blow, by insisting he has no "interest or intention" of adding the wannabe pop star to his celebrity-packed roster.

Dina Lohan, mum and manager of Lindsay and Ali, was reportedly desperate to get Ali a deal with Johnny Wright - who has made a name for himself by looking after superstars such as Justin Timberlake and The Jonas Brothers.

Last month, Dina's representative told the New York Post's PageSix column that she and Ali were expecting to meet with Wright's firm to discuss ways to further Ali's stalled music career.

Her first single, All The Way Around, from her debut Lp, failed to set the U.S. Billboard chart alight when it was released earlier this year.

But Wright claims neither he nor his company were ever scheduled to meet with Dina.

In a statement to PageSix, Wright says, "Johnny Wright would like to set the record straight regarding his involvement with Ali Lohan.

"Johnny Wright has never met with Ali Lohan, has never been introduced to Ali Lohan, nor has he had a meeting with Ali or Dina Lohan regarding Ali's music career.
