Mariah Carey Spotted With Hot Backup Dancer in First Sighting Since Break From James Packer

Mariah Carey isn't keeping a low-profile after her rep confirmed to ET on Thursday that she and fiance James Packer have hit a rough patch in their relationship.

The 46-year-old singer went out to dinner with friends at Nobu restaurant in Malibu, California, on Thursday night, where she appeared to be in good spirits. Carey sported a jaw-dropping ensemble, flaunting her slim bod in an almost completely open black top that bared her bra, and skintight red leather pants. A sassy pair of black, lace-up stilettos completed the look.

Carey was also noticeably still wearing her giant, 35-carat engagement ring from 49-year-old Packer.

Interestingly enough, Carey's backup dancer, Bryan Tanaka, was spotted out to dinner with the group. Carey reportedly "developed a close friendship" with Tanaka during her Las Vegas residency, E! News reports. An eyewitness tells ET that Tanaka walked out of the restaurant about 10 minutes before Carey did.

"It looked like they didn't want to be spotted together," the eyewitness observes.

Carey's rep exclusively told ET on Thursday that Carey and Packer have not seen each other since they got into a fight during their vacation in Greece last month. "They are trying to work it out," Carey's rep said. "Right now, they're not sure if they will stay together." However, Packer's rep told ET that this is all "simply untrue."

But a source tells ET that time apart for the couple is not necessarily an ominous sign for the relationship. "This is just two people in a relationship who are both extremely busy people," the source explains. "He travels a lot, she travels a lot. They don't spend every minute together."

Meanwhile, judging by Tanaka's Instagram, he and the GRAMMY-award winning singer are certainly close. Tanaka was at Carey's annual Halloween party on Saturday, where he posed with the singer, who was clad in a sexy devil costume.

The pair has also shared a few group moments together, such as their outing at the Essence Festival in July.

Carey's rep told ET that cheating allegations or excessive spending by Carey were not the basis of their argument in Greece.

ET spoke to Carey in June, when she said that marrying Packer later this year was "the goal," however, she noted that she had "a lot on [her] plate." The mother of two also told us she wasn't "on the prowl" for a new man after splitting from Nick Cannon in 2014, but felt a spark with Packer.

"We were talking and having a good time and I was like, 'This guy is really fun.' So it was nice," Carey shared.
