When it comes to Jon Gosselin, b*tches recognize pimpin' when he walk into the do!

Although it was a ridiculous 115 degrees in Las Vegas on Saturday, thousands of people showed up to Jon Gosselin's pool party.

"Moments" after Jon's gut made an appearance at MGM Grand's Wet Republic, several females from the VIP area approached him and hung out in his cabana while he ordered Vueve Clicquot Champagne, water and trays of food.

During the two hour douche festival, Jonny was spotted taking phone numbers and mixing drinks for the hot girls in bikinis. After the party, Jon ate at Craftsteak with his mother and friends and later checked out Cirque du Soleil's Ka.

Jon's event drew a crowd of 2,000 people who danced to rock, hip hop and house music.

There was one chick at the bash who shouted out "Team Kate." If she was hot, I'm sure Jon would try to get her number too.
