R+b superstar Alicia Keys snubbed her own album launch party on Tuesday night - because the New York bash was "too rough".

The Fallin' hitmaker left organisers of Manhattan nightspot Pacha fuming after failing to show at the party held in honour of her latest release, As I Am.

But her manager Jeanine McLean says Keys had good reason to snub the event, because the trendy venue was "a mess".

She tells New York gossip column PageSix, "She was going to go through, have a drink and celebrate as a favour to the club. But when she got there, there was no security and the crowd was rough. She sat there waiting for them to get it together for an hour."

However, a source tells the New York Post's gossip column PageSix that Keys didn't show because "she wasn't getting paid."

A representative for Pacha says, "We had an ample security team onsite and had reserved an entire area for her."
