(Cover) - EN Showbiz - Bradley Cooper and Zoe Saldana have sparked speculation they are rekindling their romance after looking "pretty engaged" during a dinner date.

The Hollywood pair called off their relationship in March after about three months of dating. It was claimed Bradley ended the relationship because he was not ready to commit.

However, sources told the New York Post that the former couple may have started dating again, after a cosy-looking reunion on Wednesday.

An insider told the US publication that the two looked "pretty engaged" as they enjoyed a meal at the East Village restaurant Empellon Cocina.

Onlookers say Zoe and Bradley stayed at the eatery for about two hours, before leaving together.

"It looked a little more friendly than a business meeting," one observer added.

Representative for both stars had no comment regarding the speculation.

Zoe and Bradley met while filming their upcoming film The Words, which is set to be released in September. (C) Cover Media
