TMZ.com has new details about the ski accident that left actress Natasha Richardson in critical condition at a Quebec hospital yesterday. The 45-year-old wife of Liam Neeson was taking a private lesson on a beginner slope when she fell. Though there was no blood or major impact, two patrollers came to her aid. "When they got there she was conscious -- smiling and making jokes," TMZ reports. It was later that the mother of two "started to complain of a headache and said she didn't feel well." She was conscious when she was transported from the ski resort but she's now in critical condition for a brain injury. Richardson is also the daughter of Vanessa Redgrave.
