No other than the hot Jennifer Lawrence who reportedly filmed a cameo for the sequel "Dumb and Dumber To" starring Jim Carrey and Jeff Daniels.

According to THR, Lawrence will play younger version of Kathleen Turner's character, Fraida Felcher.  It was convenient that the "Dumb and Dumber To" set was near "The Hunger Games" Mockingjay" lot and apparently, the enitre cast visited the filming of "Dumber."  Of course, Lawrence is starring as Katniss in "The Hunger Games" films.  

The "Dumber" sequel is a road trip movie with Lloyd (Carrey) and Harry (Daniels) taking the highway to find Harry's long-lost daughter.  The Farrelly brothers, Peter and Bobby, are returning to direct the sequel, and do you know who else is coming back?  Brady Bluhm as Billy in 4C.  Take a look at his grown-up picture below:
