Cameron Diaz and Benji Madden sure are off to a sweet start in 2015. The couple wed at their home in Beverly Hills on Monday, a source tell PEOPLE.

The pair, who have been dating since May, got engaged just before Christmas.

“Getting married is the next step when you are totally in love and comfortable with someone,” a source tells PEOPLE. “Cameron has found true happiness.”

Over the weekend, the couple hosted an intimate rehearsal dinner at their Beverly Hills pad for family and friends, including Drew Barrymore, Joel Madden and Nicole Richie, a source tells PEOPLE.

The pair were also spotted at Il Cielo Saturday night, where “they were with a small group and had a really romantic table setting with rose petals and candles,” says a restaurant onlooker. “It looked like they were celebrating.”

Diaz, 42, also celebrated her impending nuptials with a bachelorette party over the weekend, says the source. Diaz spent Sunday night at a Los Angeles-area hotel with her girlfriends.

Party rental trucks and bunches of white flowers began arriving Monday morning to the gated community where Diaz and Madden live. And celebrity wedding planner Yifat Oren (she planned the couple’s rehearsal dinner and has planned weddings for Reese Witherspoon, Anne Hathaway, Natalie Portman and Diaz’s close friend Barrymore) was also spotted arriving at their home Monday.

A huge tent was put up on Diaz’s property for the ceremony and reception – the latter dimly lit with lots of candles and mostly white flowers. Witherspoon and Gwyneth Paltrow were among several celebrity guest in attendance. Benji’s twin brother, Joel Madden, was also spotted arriving at their home in the early afternoon.

“There is a lot of security and they are trying to keep the wedding hush-hush by telling neighbors that Cameron is having a pre-Golden Globes party tonight,” another source tells PEOPLE. “It will start past dark tonight. They are setting things up in the lush backyard.”
