Jenny McCarthy has been seen getting "very cosy" with a mystery man.

The former Playboy model - who split from Jim Carrey, her partner of five years, last month - was spotted yesterday (06.05.10) looking very close to a new guy while on holiday in Las Vegas with her sisters and friends.

Jenny, 37, had been enjoying dinner with her pals at the N9NE Steakhouse, before they headed to the Playboy Club where the blonde beauty hooked up with the hunk.

A source said: "After dinner, Jenny headed to the Playboy Club for some martinis and was seen getting very cosy 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."
