Jenny was spotted yesterday getting "very cozy" to a new guy while on vacation in Las Vegas with her sisters and friends.
A source said: "After dinner, Jenny headed to the Playboy Club for some martinis and was seen getting very cozy kissing an unknown guy."
Jenny previously revealed her break-up from Jim was amicable and she was "grateful" for their time together.
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."
After five years together, you would think it would take more than a month to move on, but not in Hollywood! Wonder how Jim feels about this?
