But while many were keen to romantically link the former lovers, it seems Cameron has a new relationship she was keeping under wraps.
This week the leggy blonde was spotted leaving the Manhattan apartment of baseball player Alex Rodriguez, blowing the cover on their budding romance.
Alex – known as A-Rod – was most recently linked to Nine actress Kate Hudson, and before that was seen in the company of queen of pop Madonna.
Both Cameron and her new beau were evidently keen not to be photographed together, with the 37-year-old actress exiting the building first clutching what seemed to be overnight bags.
She was followed by the handsome 34-year-old sports star who attempted to hide his identity by ducking behind a large black umbrella.
Cameron – dressed casually in a blazer and jeans – was first linked to Alex in February when the pair were spotted dancing together at a Super Bowl party.
But they have evidently been taking steps to keep the relationship out of the spotlight.
According to the New York Post, the couple had spent the previous evening in the company of Cameron's The Holiday co-star, newly-single Kate Winslet.
"They all shared a delicious meal and several bottles of French red wine," a source told the paper.
