The 'Toxic' hitmaker appeared to give lover David mixed signals as she wore a rude jumper with the words, "F*ck off lover boy", emblazoned on the back.
In the snap, Britney turns to the wall with a mischievous look on her face, while David points to the phrase. Captioning the photo, Britney said: "Sorry not sorry ;)."
But the 32-year-old quickly told fans that she was just joking around, and later was all smiles as she cuddled up to David in another picture.
She said: "Just kidding. Love you D!!!"
But that wasn't if for the couple, as later, David had the opportunity to show off his funny side and wore a brown wig to match Britney's dark locks!
Taking to Instagram, Britney said: "David had his hair done for my show!"
Britney is currently in Las Vegas on her two-year residency at the Planet Hollywood Resort and Casino, where she is scheduled to perform more than 50 shows a year for her 'Piece of Me' show.
Popstar Britney unveiled her brunette hair last week while promoting her new Valentine's Day fragrance, in which she urged fans to get "naughty and nice".
In November last year, Britney gushed about David for the first time during a talk on US show, Entertainment Tonight.
"I'm in love," she said. "I like the fact that David is very stubborn and he's stuck in his ways."
