Christian Aguilera has nothing but love for former pop star rival Britney Spears.

This season, the two singing divas will compete for ratings on their shows "The X Factor" and "The Voice."

"I came up with Britney, we were very close," Aguilera told reporters during a recent press conference in California, according to VIBE. "Our paths have always crossed. They'll continue to cross. I welcome her to this family of fun and entertainment and finding new talent.

"Britney's a pro," Aguilera continued. "She's going to give great advice."

As a new judge on "The X Factor," Spears may feel a little pressure to bring her A-game.

Recently, RadarOnline.com reported that Spears seemed "robotic and out of it" during a two day long commericial shoot last week at the Queen May in Long Beach, Cali. She was shooting for her new fragrance.

"Britney didn't interact with the cast or crew at all during the two day shoot and she seemed to be just going through the motions when the camera was rolling, and seemed out of it," an eyewitness tells RadarOnline.com.

"Britney was almost robotic in her movements. Britney's fiance, Jason Trawick was along for the shoot and everyone thought at first he was her assistant because she spent so much time huddled up with him when not filming. Britney must have smoked at least a pack a day during the two day shoot and was always smoking when not filming. Security was very tight and Britney had more bodyguards than usual and was kept out of sight from visitors to the Queen Mary."

"Britney spent a lot of time in hair and make-up and nervously bit her fingernails and kept smoking throughout," the source says.

"She looked amazing though and her fans will love the commercial. Britney did was what asked of her and the end result worked, but the crew wondered why there was such a heightened presence of security. It was just a bit over the top and security even stayed after the shoot to make sure that no one took any pictures of Britney as she left," source added.

Spears' new Elizabeth Arden television commercial will premiere at the beginning of September.
