She played Laura, the girlfriend of Butch Cassidy on a 1958 episode, "The Outlaw Legion," of the syndicated western Frontier Doctor.

She also appeared in two Perry Mason episodes, titled "The Crooked Candle" and "The Purple Woman".
Singleton guest-starred on My Three Sons, playing two different characters who had recurring roles throughout the long run of the show. She originally played the mother of Meredith MacRae whose character Sally Morrison married original oldest son Mike Douglas (Tim Considine) in the 1964-65 season.
