Ricky

From Memory Alpha, the free Star Trek reference

Ricky was a female hologram, a character in Tom Paris' holodeck holo-program, Chez Sandríne. Paris was fascinated with Ricky and made sure to include her in every program he created. She made Sandríne jealous with her outward affection toward Paris. She also told Harry Kim that Paris was hustling him at pool. (VOY: "The Cloud", "Meld")

Ricky was played by actress Angela Dohrmann.
