Sam reportedly tried to get her flirt on with Harry, but got a pretty icy response, according to Heat magazine.
The two were at Lily Allen's part in LA earlier this month, with an inside source dishing (via Unreality TV) that Sam "made it a mission" to talk to Harry: "When Sam saw Harry go to the bar with some friends, she went straight up to him and introduced herself...whispering in his ear and being flirty."
The source dished on Hazza's reaction, which probably wasn't quite what Sam expected: "Surprisingly, Harry didn't seem interested and seemed to have his sights set on someone else. It looked like he kept trying to fob her off and get away, but Sam was incredibly persistent and draped herself over him."
That persistence didn't pay off, however, as the insider explained, "Eventually his security guy came to detach her from him, asking her to 'move on.'"
Ouch. Adding insult to injury, she reportedly gave it a last ditch effort when he was about to leave, "asking him back to her hotel bar for some drinks, which he politely declined before leaving."
