Mariah Carey and her fiancé James Packer shared a kiss before her show in Las Vegas Sunday. The pop star performed the show as part of her Las Vegas Residency at Caesars Palace. But, just before her performance, Carey’s billionaire fiancé came backstage and kissed her.

Though it was their first Valentine’s Day as a couple, it was work as usual for both of them. However, the 48-year-old businessman made sure that his ladylove was looked after before her show.

The 45-year-old singer took to Instagram and shared the picture with her fans. In the picture, Carey appears to be uneasy and hesitant as the pair share an awkward kiss. The pair’s lips are not quite touching and while Packer has his hands on Carey’s hips she is not holding him.

The pop star wore a gold LaBourjoisie dress for her performance. The strapless number also features a thigh-high slit and shows off her figure. Her blond locks are left loose over her shoulder in center-part and she wore pink lipstick.

In the picture, the pop diva who has two kids shows off a diamond bracelet and her 35-carat diamond engagement ring. The singer flashes a lot of cleavage in the photograph. This was Carey and Packer’s first Valentine’s Day as an engaged couple.

Carey accessorized with a lot of diamond jewelry for the concert and completed her look in a pair of strappy platform sandals in gold.

The singer and her Australian billionaire beau got engaged at a party on Jan. 21 after a whirlwind romance of seven months.

Earlier, Carey also posted a picture with Beyoncé at the Heartview Global Charity Gala held at Skirball Cultural Center in Los Angeles on Thursday night. During the charity auction, both the ladies who have the same business manager Jon Schwartz got into a bidding war over a Ray Charles portrait. Also, TMZ reported that Carey and Queen Bey said that a duet needed to happen and they made plans to collaborate in the future.
