Robert Blake better make himself comfortable in that jail cell of his: The onetime Baretta star was denied bail at a hearing Wednesday in Los Angeles. "There is proof of his guilt and the presumption is great, for bail purposes only," Superior Court Judge Lloyd Nash said. "That does not mean I believe he committed this offense, or that I think he's guilty." Nash will reconsider the bail request after a preliminary hearing Dec. 11. Blake is awaiting trial on charges that he murdered his wife, Bonny Lee Bakley.
