Kelly of morning TV

RIPA

Think of the co-host who shares a last name with a famous talk show host’s wife.

This clue refers to Kelly Ripa, a well-known television host who co-hosted Live with Regis and Kelly (later Live with Kelly) for years. The answer is just her last name, "RIPA," which fits the crossword’s brevity. Morning TV is a direct hint to her long-running daytime talk show career.
