Sources close to the situation say Kevin Hart is facing at least four months of aggressive physical therapy in the aftermath of his scary car accident. According to The Blast, Hart's surgeons had to fuse the comedian’s spine in three different places after it was determined he endured multiple fractures in his back. While the surgery was a success, an insider confirms the recovery and therapy will be “very painful.” While fellow comedian Tiffany Haddish tells ET that Hart is “already walking,” sources tell TMZ that the star is “still in excruciating pain.”
