Back With A Vengeance! Diva Christina 'Horrendous' To Staff During 'The Voice' Shoot

The Voice Season 10 is premiering in less than a month, and an on-set source told RadarOnline.com exclusively that they are already having troubles with Christina Aguilera!

"The filming of the new TV spot promo with Christina was absolutely horrendous," the source said.

"She showed up late and acted like she owned the shoot. The entire thing had to be about her or else she would have flipped out."

"Christina insisted on wearing her own wardrobe and using her own hair and make-up team," the insider said, adding, "She just would not take any direction for the shoot and wanted it to center around her. And so it did."

As RadarOnline.com was the first to report, last season sparked the relationship between judges Blake Shelton, 39, and girlfriend Gwen Stefani, 46 – who was replaced this season by the 35-year-old "Fighter" singer, yet is still going to appear on the show as a mentor on her country superstar boyfriend's team.

This season, the other two judges – Adam Levine, 36, and Pharrell Williams, 42, as well as Shelton – "just let Christina have her way because it is much easier than arguing with her," the source told RadarOnline.com.

"Filming with Christina is night and day from filming with Gwen and a lot of people are just kinda bummed that they brought her back."
