"Silver Linings Playbook" star Cooper, who turns 38 Saturday, and Saldana, 34, who reprises her role as Communications Officer Uhura in this May's "Star Trek Into Darkness," had reportedly planned to spend the holidays with Cooper's family in Paris, but Saldana instead spent New Year's Eve in Miami with friends and her own family.
People magazine said Thursday that Saldana and her group ate privately at the restaurant Catch, then retired to the James Royal Palm hotel pool area, where the actress spent time with Miami Heat guard Dwyane Wade and his girlfriend Gabrielle Union, and Wade's teammate, Chris Bosh, and his wife Adrienne Bosh.
Representatives for Cooper and Saldana did not respond to requests for comment.
After meeting on the set of "The Words" in 2011, the two reportedly began dating early last year and broke up in March. In September, however, they were photographed arm-in-arm leaving a Hollywood theater after seeing "The Master," and reportedly were back together.
Cooper -- People's 2011 "Sexiest Man Alive" -- was married to actress Jennifer Esposito for four months from 2006 until she filed for divorce in 2007.
In November 2011, Saldana announced she had broken up with her partner of 11 years, My Fashion Database chief executive Keith Britton.
