Is Leonardo DiCaprio single and ready to mingle? It sure looked that way last night. The actor made a late-night appearance at Hollywood hot spot MyHouse, arriving around 12:40 a.m. with a group of guys. Leo, low-key in a baseball cap and a few days of stubble, grabbed a table and ordered a bottle of vodka to share with his boys. But as the night wore on, he invited a few lucky ladies to join the party... About an hour after his arrival, Leo's security guards ushered a few pretty young things (who seemed to be handpicked by the actor himself) from the dance floor to his table. He was seen whispering and sitting close to both a mystery blonde and a brunette for the rest of the night. Maybe that means he and Bar Refaeli really have pulled the plug on their on-again, off-again relationship. http://www.eonline.com/uberblog/hwood_part...flirt_mode.html
