According to the New York Daily News, the 29-year-old actress "laughed and giggled" with the New York Yankees baseman as they watched Mariah Carey perform at the opening of the Fontainebleau Hotel in Miami.
"Hudson had her arms completely wrapped around A-Rod's waist and every time he leaned over to talk to anyone she would pull him back toward her," said a source. "They were laughing and giggling all night."
When Colombian model Sofía Vergara leaned over the table to speak with Rodriguez, Hudson reportedly whispered into his ear to regain his attention.
