Miley Cyrus jealous of Jennifer Lawrence's 'friendly' relationship with sexy 'Hunger Games Catching Fire' ex-fiance, Liam Hemsworth?

Get this - "Wrecking Ball" songstress Miley Cyrus is "jealous" of "Hunger Games" beauty Jennifer Lawrence. Why? Because the stunning Academy Award winner has an awesome relationship with "Catching Fire" co-star Liam Hemsworth (who also happens to be Cyrus' ex-fiance)!

A recent issue of Life & Style magazine blares the headline: “Watch Out, J-Law! Miley’s On the Attack.”

Apparently, the 21-year-old twerker is "fuming" over Hemsworth's friendly, budding relationship with Lawrence. The Australian heartthrob continues praising Lawrence in several media appearances, and the infamous gossip rag claims it's like a "dagger in the heart of his ex-fiancée."

"To her, his kind words feel like a personal dig," the magazine reveals. Cyrus "has grown 'insanely jealous' of her ex's relationship with Jen."

A supposed Life & Style source explains that Cyrus "desperately wishes that she and Liam could get back together... [She] feels like Liam got over everything too quickly, and she's very insecure and jealous of Jennifer."

Another close "friend" of Hemsworth's insists that the actor even wants to pursue dating Lawrence.
