Wednesday on TV: ‘Crazy Ex Girlfriend’ star asks ‘Whose Line Is It Anyway?’

Rachel Bloom is one of the most talented people in television. She's not just the star of "Crazy Ex-Girlfriend," she's the co-creator, an executive producer, and a writer.

And she co-writes the songs.

Which is why the Television Critics Association just gave her its award for Outstanding Individual Achievement in Comedy over the weekend.

Tonight, she's a guest on "Who's Line Is It Anyway?" (8 p.m., CW/Ch. 30) — a show for which she seems perfectly suited.

The Summer Olympics are still going strong, of course. Check out this accompanying story for television highlights.
