The actor - who recently split from long-term partner Jenny McCarthy - amazed revellers at New York nightspot Pacha when he started getting "hot and heavy" with two mystery females in the early hours of Sunday morning. A source told the New York Post newspaper: "He arrived at 3am with an entourage of at least 10 women. "Once in the VIP area, he turned his attention to a pretty blonde who looked a lot like Jenny and a hot brunette. Things were getting so hot and heavy, someone shouted, `Get a room.` Jim just burst out laughing." It is unlikely that Jim`s antics will upset Jenny, as the blonde beauty is currently on the hunt for a mystery man. The 37-year-old star was spotted kissing an unnamed hunk in Las Vegas recently, and has admitted she has no idea who he is either. She tweeted: "Yes, I kissed a mystery man in Vegas. "Everyone wants to know who he is or what his name is┘ So would I." Jim announced on twitter last month that he and Jenny had ended their five-year relationship. He wrote: "Jenny and I have just ended our 5yr relationship. I`m grateful for the many blessings we`ve shared and I wish her the very best. S`okay! "Be of good cheer folks! It`s a beautiful world, and we`re all gonna get what we need the most! (sic)"
