Britney Spears' new single "Work B--ch" seems to be an instant hit. 

After teasing it for about a week on her Instagram page with a series of shots, the singer finally released her latest music video on Tuesday night, during the iHeartRadio Music Festival telecast.

In the four-minute video, the 31-year mom of two shows off her enviable physique, while strutting and posing through the new video. She wields a leather whip at one point and even dances among sharks. The singer struts in sexy ensembles, flanked by all female dancers.

The video includes a nod to her upcoming Vegas stage show. The singer works it on a balcony of the Planet Hollywood, where she will take the stage starting in December. The video has been viewed on VEVO  over six million times since its release.

Spears recently announced her two-year residency, officially called "Britney Spears: Piece of Me."

"This is the best-selling show in the history of Vegas," said Spears manager, Larry Rudolph. "We have a great thing going here. We have a great show we're putting together. We have nothing but green lights ahead of us. We have amazing sales."

Spears dished to Ryan Seacrest about the residency during a recent appearance on his morning radio show.

"We are going to have all the works-snow, water, rain, everything," she said. "Every time I do a show, I like to really bring it. I love to put on a show that will really entertain fans. We want the feeling that fans will be in the show with me. We're going to have a cool set-up for them with a party vibe so they are really there with me."

Celine Dion, the ultimate Vegas diva, offered a few words of wisdom to her younger counterpart. The 45-year-old chanteuse told "ET Canada" that Spears doesn't need any advice from her, but offered a few tips anyway.

"She's been on stage, she's shook it all out. She's very talented and knows exactly what to do," Dion said before proceeding to say she hopes Spears can "find wonderful people who can help her find a balance between the artist that she is and the mother. Try to find an emotional balance and cope with those two and be the best of both worlds, and I think she can really do it."

Spears Planet Hollywood performances kicks off on Dec. 27.
