Keri Hilson Screams at Assistant Over Wardrobe

Considered squeaky clean by diva standards, Keri Hilson appears to be building a little bit of a rep, appearing in headlines once again for acting out.

A month after she raised the ire of mourning Amy Winehouse fans by tweeting that she had "resurrected" the recently deceased singer to party with her, Hilson popped up in the New York Post yesterday (Sept. 1), for losing her temper at her assistant after a performance in Las Vegas.

According to the Post, Hilson narrowly avoided a scrap with her assistant after performing at Haze at the Aria Resort and Casino on Saturday (Aug. 27), when she realized that she had neglected to remove a tag from the black harem pants she wore on stage.

"Hilson lost it," revealed the Post's source. "She was screaming at her assistant for 'not being able to do anything right.' [She] railed that the assistant also forgot to 'pack her eye drops and throat spray.'"

However, her aide apparently did not take the outburst sitting down, reportedly countering with an "Oh hell no!" before Hilson's bodyguard and manager were able to intervene.

The 'Pretty Girl Rock' singer's rep has since denied that any such altercation took place, telling the Post, "Keri did ask her assistant to bring her eyedrops/throat spray as she was feeling under the weather, but there was no altercation. Keri has had the same road staff, from assistant to security, for a few years now."

Following the show, Hilson tweeted her appreciation for the fans who came out that night, and gratitude to the club's staff, "Shout out to all the PARTY PEOPLE at HAZE tonight!!!! Much love to promoter, mgr & staff for takng great care!!"

Hilson is currently finishing up the second leg of Lil Wayne's I Am Still Music tour, which hits Mountain View, Calif., tonight, with Rick Ross, Far East Movement and Lloyd. The tour concludes on Sept. 11. Check out the rest of the dates here.
