Saldana, 34, and Cooper, 37, originally dated for three months after filming "The Words" together and split in March last year before getting back together in September, reported the New York Post.
"Zoe had planned to spend the holidays with Bradley and his family in Europe. They all were going to Paris, but things didn't work out between them. Zoe spent New Year's Eve with friends in Miami," a source said.
Whereas, Cooper is believed to be in Prague shooting a commercial.
Saldana, who has been shooting "Blood Ties" with Mila Kunis, ushered the New Year in at a South Beach dinner then had the countdown at the James Royal Palm on Collins Avenue.
"If Zoe was upset over the split with Bradley, she didn't show it," the source added.
Saldana, who split from fiance and love of 10 years Keith Britton in November 2011, was joined by supermodel Karolina Kurkova.
