LaBeouf was maneuvering his heavy black truck when he bumped the rear section of comedian Jesse Coccoli's Nissan while merging near the intersection of Los Feliz Blvd. and Hillhurst Ave., she told Celebuzz in a telephone interview. Coccoli recounted the incident live in her Twitter feed and provided more details in an email exchange with Celebuzz.

Representatives for the star, however, disputed her account, insisting that LaBeouf was not even in the neighborhood, much less at the wheel or involved in an accident.

"This story is completely fabricated," a spokeswoman for LaBeouf told Celebuzz last night. "Shia was in Santa Monica with friends for the afternoon in question. This must be a clear case of mistaken identity."

Coccoli said she stood by her story. In recounting the incident to Celebuzz, she said she did not recognize the star initially. "I think I said, 'I can't believe you just hit my car going two miles an hour,' and realize, it is him," she said.
