In Jennifer Lawrence's latest collaboration with David O. Russell, the "Joy" comes more from the name of the film's subject, the real-life Miracle Mop inventor Joy Managano, than a feeling of great pleasure or happiness. (She is a struggling single mother of three throughout most of it, after all.)

So when MTV News caught up with Lawrence during a recent press day for the film, we made sure to lighten up the mood by asking her which of life's finer things -- think food, drink, movies, and boy bands -- make her feel the most joy. Enjoy the footage, and be sure to let all of your Backstreet Boys-loving friends know once and for all that NSYNC has got the flow, and BSB have got to go.

"Joy" hits theaters nationwide on Christmas Day.
