Jimmy Kimmel's ABC late night skein may be temporarily idled by the writers strike, but picket lines can't stop the march of time. Kimmel toasted the onset of his forties with a birthday bash at Tao in Las Vegas on Nov. 9.

According to IMDB, the big 4-0 for Kimmel officially arrives on Tuesday (Nov. 13). Too bad he won't have a show to mark the occasion and show off pics like the one at left with his mom and dad, Joan and Jim Kimmel, and galpal Sarah Silverman apparently mistaking his cheek for a slice of cake (or maybe not?). According to an ABC rep, "Jimmy Kimmel Live" is taking it day by day but will fer sure be a repeat on Tuesday.
