Breath mints, apparently.
US Weekly reported Thursday that the Pitt, 49, gave Jolie, 37, Eat Whatever, a vegan, gluten free, sugar-free breath-freshening product for Valentine's Day.
"It is sort of a joke -- and not," a source said. "He always teases her that she has bad breath."
"It's a joke gift," the source added, "he'll also get her something more serious."
Eat Whatever includes a mint and swallowable gel cap.
Pitt's "joke gift" might be a funny inside joke, but it doesn't quite top the actual California waterfall that Jolie bought him for his birthday last year.
