Kristin Chenoweth skipped the Los Angeles premiere of her new film Hit & Run on Tuesday after undergoing her first physical therapy session for a serious head injury.

The singer/actress was hospitalised last month when she was hit by a falling piece of lighting equipment on the set of U.S. TV drama The Good Wife.

Chenoweth announced on Monday she has quit the series as a result of ongoing complications from her injury, and she was spotted out in New York the following day wearing a neck brace as she headed to a medical centre for her "first day of physical therapy".

The actress then opted for an evening of rest after her session rather than heading to the West Coast for the red carpet launch of her new movie.

Her co-star Kristen Bell reached out to her injured pal on Twitter, writing, "Heading to the Hit and Run movie premier (sic) - wish you were here!!!!"

The blonde quickly replied, "I am in spirit. And so proud to be a part of this movie. Beyond happy! To all in the movie Hit and Run: wish I was at premiere tonight! Have fun!" (CL/WNTWT/LR)
