Britney Spears may have told boyfriend David Lucado, "You better bark, b—h," during her Vegas show on New Year's Eve. The pop star brought her main man up on stage and kept him chained up on a tight leash and on his hands and knees as she sung and danced behind him.

As you can see in the photo here — taken at the the December 31 iteration of her residency at Las Vegas's Planet Hollywood Resort & Casino — her boyfriend of nine months was all smiles as the 32-year-old singer took him for a walk.

Brit Brit just embarked on the two-year gig in Sin City. The show opened on December 27, and she's scheduled to perform 100 shows throughout 2014 and 2015.

Meanwhile, she released her eighth album, Britney Jean in December, with singles including "Work B—h" and "Perfume.” The bad news: It's her lowest-selling album of her career thus far.

A month ago, Britney told talk show host Ellen DeGeneres how she and David first got together. "I met him at a party," she recalled. "My friends brought me up to him … They brought me to him just to introduce me to him."

Hmm… doesn't sound like chains were involved that time!
