New York, June 29 Rumours are rife that 'Transformers' co-stars Megan Fox and Shia LaBeouf are an item.

Both Fox and LaBeouf were seen sitting side-by-side during a dinner with 10 pals - including director Oliver Stone - at Nobu on June 25, and they seemed quite into each other.

"They definitely seemed into each other," the New York Daily News quoted a witness as saying.

Another spy added that, while partying at a Rose's bash in West Hollywood earlier in the week, "Shia couldn't keep his eyes off of Megan: He literally watched her like a hawk all night."

Meanwhile, 'Transformers: Revenge of the Fallen' has topped the weekend box office after raking in 112 million dollars. (ANI)
