Jennifer Lawrence's Hair Goes Sky-High: Bradley Cooper, David O. Russell Reunite With Actress (PHOTO)


Jennifer Lawrence's hair is so big it's full of secrets! (That's a "Mean Girls" reference, by the way.)

The 22-year-old Oscar winner was seen with her hair up in a glamorous 'do on March 25 while heading to the set of her latest movie which is so new, it doesn't have a name yet.

The movie reunites "The Hunger Games" actress with her "Silver Linings Playbook" co-star, Bradley Cooper, and director, David O. Russell. Wait for her to be nominated for a third Academy Award next year.

Jennifer is no stranger to the glam life; she's the new face of Dior, wowed us with two different looks at the Toronto International Film Festival last year and flashed some major sideboob at this year's Independent Spirit Awards.

Although she has had major fashion moments, Jennifer is not impervious to style mishaps. Most of us will never forget the voluminous Dior dress that caused Jennifer to slip on the stairs while walking up to the podium to accept her Best Actress Oscar for "Silver Linings Playbook."

And we definitely won't forget the time at the SAG Awards when her Dior dress "ripped" and revealed a sheer panel that showed off Lawrence's legs.

We bet that JLaw wishes she were back on vacation in Hawaii, wearing comfy loose pants and a roomy tee.
