Cameron Diaz dating Benji Madden has possibly led to an engagement as the 42-year-old actress showed off a massive ring on a public appearance on September 3. Meanwhile, the "Sex Tape" movie's release was very timely in light of the celebrity nude leak in recent days.

According to the Western Morning News, the Cameron Diaz dating Benji Madden just got serious when the "Sex Tape" star wore a rock on her left hand at the Corinthian Hotel in London.

But Cameron Diaz has not really made any announcement in relation to the engagement rumors.

Meanwhile, the release of "Sex Tape" movie, which chronicles what happens to a couple when their sensitive video was sent to all their friends and acquaintances, coincided with the celebrity nude leak that involved many stars.

During her appearance in London, said Western Morning News, Cameron Diaz slammed the celebrity nude leak as a major violation of privacy for the stars involved, notably Kate Upton, Jennifer Lopez, Cara Delevingne, Selena Gomez, Victoria Justice, among others.

She also said that those who view and share the files should consider how they feel if someone dear to them is the victim.

The independent.co.uk said that while "Sex Tape" had a weak box-office performance in the US, it's actually "wittier and less smutty than its reputation might suggest." It also said that the movie is very timely, considering the fact that more and more videos of couples in their intimate moments are posted online.

According to People magazine, Cameron Diaz dating Benjie Madden is not just going to be a summer fling as the couple thinks that marriage seems to be next progression in their relationship.

"It's early but they have talked about marriage. Benji spends so much time at Cameron's that it seems he now kind of lives there," the magazine said, quoting an insider. "Cameron hasn't looked this happy for years."
