Prince Harry is set to party with some of America's sexiest women soon!

Looks like the 28-year-old prince's relationship with socialite Cressida Bonas will be put to the test as Harry takes a trip to the U.S. in May. New York's Mayor Michael Bloomberg is reportedly going to welcome the royal by throwing the hottest event of the year that will surely be the talk of Tinseltown.

The fun-loving bachelor will be partying with Hollywood's hottest leading ladies, including Oscar winner Jennifer Lawrence (who he apparently has a crush on!), High School Musical sweetheart Vanessa Hudgens, buxom actress Scarlett Johansson, and a few dozen more sexy stars.

Another good-looking star set to welcome Harry at the Big Apple in a lavish City Hall reception is 20-year-old swimsuit model Kate Upton. Cressida better watch out because Upton has once said about that the eligible prince is "too cute for words."

Bloomberg's aides have sworn the guests to secrecy about the soiree until the full itinerary of Prince Harry is completed.

Apparently, not all could be kept hush hush on the subject as a close source to one of the guests revealed to Daily Star, "The party for Harry is the talk of Tinseltown and is being viewed as the hottest event of the year. There are some household names who would give their eye teeth to be on that list."

Last week, rumors of the Bonas and Middleton sisters having a feud have been spreading on tabloids. However, dance student Cressida seems to have passed the royal big test by keeping mum about her relationship with Harry in front of the press. The 24-year-old is among the list of looker blondes Harry has wooed, but many believe she is "the one" after he was reportedly asking love advice from sister-in-law Kate Middleton.

Now it seems like it's Harry's turn to prove he is "the one" for Cressida, as he attends the biggest party of the year in the U.S.
