Lady Gaga and Bradley Cooper Were Reportedly "In a Corner Together All Night" at an Oscar Party This Weekend

Lady Gaga (opens in new tab) and Bradley Cooper grew their reputation as "closest costars" at CAA’s pre-Oscars party on Friday night, where they reportedly spent their time talking "in a corner together all night," according to sources who spoke to Us Weekly (opens in new tab). 

The intimate, corner convo only fueled rumors that there are real-life romantic feelings between the costars, whose onscreen chemistry sizzled in A Star Is Born (opens in new tab). 

"They looked so close, they almost seem like a couple,” the source told Us Weekly of Cooper and Gaga's interaction at the party. Cooper's long-time girlfriend, Russian model Irina Shayk (opens in new tab), with whom he shares a daughter, 23-month-old Lea De Seine (opens in new tab), was not in attendance at the party. Lady Gaga's recent ex, Christian Carino, was however.

"Christian Carino walked into the party…said hi to Gaga at one point," the party source said. "But it was brief and then he went to another room."

Gaga (opens in new tab) and Carino's split is still very fresh; news that the former couple had decided to call off their engagement broke last week.
