Actress Cameron Diaz is said to have "found true happiness" after her marriage with Benji Madden, which took place earlier this month.

The duo married Monday.

"When you see them together you can see how happy they are. Cameron has found true happiness," a close friend of the couple told people.com.

The duo, who got married after just seven months of dating, wanted their nuptials to be romantic despite having a star-studded ceremony at the "Sex Tape" star's lavish mansion here in Beverly Hills.

"It all felt very down to earth and sweet. It was a big wedding but still managed to feel personal. Everyone was excited to be part of it," said another source.

Another friend added: "Benji adores Cameron. And she can be herself with him. For a girl who was happy being single, Cameron has fallen in love."
