Bradley Cooper and his Code 39
costar Renée Zellweger
said "adios" to Barcelona
and returned to the United States, where the two spent their weekends at separate events.
On Saturday, the actress attended the premiere of her new movie, My One and Only
at a private estate in Wainscott, N.Y., sans Cooper, who was in New Jersey at Alyssa Milano's wedding.
The actor is friendly with her groom, David Bugliari, a Hollywood agent.
Zellweger kept tightlipped about her blossoming romance with Cooper. (When asked about her trip, she only quipped, "time to go!) But the actress did take her parents along to the screening and dinner, which was held at the Blue Parrot in East Hampton.
While in Spain last week, Zellweger and Cooper were spotted at the luxury Hotel Arts Barcelona – where they got cozy. Cooper kept his arm around her, while Zellweger tucked her hand into his back pocket.
"They make a great couple," a friend of Zellweger told PEOPLE last week. "They get along well; they have fun together, and they're really happy."
