The 37-year-old beauty - whose five-year romance with actor Jim Carrey ended in April this year - admits she feels more comfortable going out in skimpy clothes and showing off her assets now she is stepping out alone.
Wearing a bra-style top with a short mini-skirt, she said: "I`m enjoying the singlelife tremendously! Look at me in this outfit. Would I not be hitting this? Come on. I have one more year to pull off an outfit like this, so better hit it while it`s hot."
Jenny - who has an eight-year-old son Evan with ex-husband John Asher - also revealed she feels more "peaceful" since she left Los Angeles and set up home in Las Vegas.
She added to Us magazine: "I really love it. I was never really a fan of Los Angeles. Coming out to Las Vegas, believe it or not, I feel more peaceful.
"Evan has seen every single show and he`s gone to every casino, every arcade. There really is only so much you can do with a kid."
Jenny and Jim called time on their relationship in April, with the blonde beauty taking to twitter at the time of the split to say the `Bruce Almighty` star would always be her "leading man".
She said: "I`m so grateful for the years Jim and I had together. I will always keep Jim as a leading man in my heart."
