Now that Kim Kardashian
and Kris Humphries are finally divorced
, the basketball player is single and ready to mingle – and the women of Miami couldn't be happier.
On Saturday, Humphries stepped out at the SLS Hotel South Beach's Hyde Beach, where he was swarmed by so many bikini-clad female fans, "a security guard was stationed to keep them at bay," an onlooker tells PEOPLE.
While Humphries appeared to be getting a kick out of the commotion, he was more focused on having fun with friends than finding his next love interest.
"Kris loved all the attention, but didn't take it too seriously. He was more interested in enjoying time with his friends," a source says.
But as Humphries and crew sipped cocktails, the crowd grew increasingly rowdy. "The girls were so excited, they were doing chicken fights in the pool to get his attention," the source adds.
