London, Oct 17 : Prince William reportedly turned flirtatious as soon as he saw Paris Hilton at a London nightclub.
The 26-year-old invited the hotel heiress to his table after spotting her walk in with singing pal Christina Aguilera.
According to a source, the prince even tried flirting with Hilton at Mayfair club Whisky Mist.
"From the moment she walked in, William only had eyes for her," the Sun quoted a source, as saying.
"Every other girl in the room trying to get his attention seemed to disappear. He was speaking very close to her and was really charming.
"He kept saying to his friends that she was much more beautiful in the flesh. He told some pals how sweet he thought she was and really wasn't how he had imagined her to be," he added.
The Prince's brother Harry, 24, and Zimbabwean girlfriend Chelsy Davy, 23, then came over to meet the star, who is in London filming telly show 'My New British Best Friend'.
"They were both being really friendly - and Chelsy especially seemed really thrilled to meet Paris," the source said.
