"Nobody has time for boys, honey," the L'Oreal spokesperson told E! News at the Cannes Film Festival.
Despite rumors that the 38-year-old was getting close with Ready for Love bachelor Ernesto Argüello, Longoria admits her priorities are with education and producing.
"I'm still writing my thesis so I will forever be engaged in education and I really loved every moment of the journey," the California State University, Northridge student said.
In addition to a busy workload at school, Longoria is also gearing up for her new summer Lifetime series, Devious Maids, where she serves as an executive producer.
"I don't know if I'm going to be in front of the camera this year, maybe next year," Longoria said. "I really loved being behind the camera… It utilizes my business brain and I've had some really fun projects."
