Mariah Carey was a diva about photos at private Karl Lagerfeld show

Mariah Carey performed Monday during a private dinner for Karl Lagerfeld at the Boom Boom Room in front of guests including Naomi Campbell, Gigi and Bella Hadid, Baz Luhrmann and Mario Testino, but made sure fotogs only got her good side.

“She asked photographers to move to the left side of the room as she preferred to be shot from the other angle when she performs,” said a source at the V Magazine-hosted event.

A very Barbra Streisand move (who only likes to be shot from her “good side,” also the left).

Another source said Carey’s boyfriend Bryan Tanaka acted as her handler and approved pics of the star, “He was looking at each photo and saying ‘yes’ or ‘no.’ ”
