New photos of Catherine Zeta Jones strolling on the beach in bright yellow bikini have many speculating that the 37-year old actress has recently had her breasts surgically enhanced.

Already several experts have weighed in with their opinion, with the general consensus being that she had to have had surgery.

Plastic surgeon Apostolos Gaitanis said: "There is a considerable difference in the volume of the breasts. She has put weight on over the years but it looks suspiciously like she has had breast augmentation because the breasts are full and have more volume. They look firmer and project to the front. They are very full, which is a sign of a boob job".

A spokesman for Jones was not yet available for comment.
