In the wake of the shocking news that she split with her fiancé, Star magazine has exclusively learned that Zoe Saldana and Bradley Cooper were recently spotted getting hot and heavy!

The Avatar beauty posed happily by the side of Keith Britton on September 14, but just two nights later, she and Bradley were "acting like two high school kids going steady," in an exclusive Manhattan nightclub an eyewitness told the magazine.

"The way she and Bradley were sharing affectionate contact, you certainly wouldn't have guessed that Zoe had a fiancé at the time," the source said.

Zoe, 33, and Bradley, 36 arrived at the club at 3am. "They were in a group of about 20 people, but it was obvious from the start what was going on between Zoe and Bradley.  They were casting sexy smiles at each other, and every time they were within arms reach, they made sure to give each other a sneaky little rub on the shoulder or hip.  It was like they were sharing naughty little moments."

Zoe Saldana has split from boyfriend Keith Britton after 11 years together.

The Avatar actress, 33 and entrepreneur Britton, 35, revealed their engagement in June 2010, but have now ended their romantic relationship all together.

In a statement, Saldana's rep called the break-up "amicable."
