Jessica Alba and husband Cash Warren’s families came together for the first time on Friday to celebrate the couple at their Beverly Hills home.

Though they officially wed last summer, Friday’s event served as a formal reception to “celebrate their love and commitment to each other,” a partygoer told Usmagazine.com.

Guests, including newlywed Without a Trace Star Roselyn Sanchez, were asked to arrive before 7 p.m.

At the event, both Alba and Warren spoke about their relationship before turning things over to their fathers, who each expressed happiness over the union of the two families. Later, a mariachi band played.

“There were no tears,” the partygoer said, “just lots of happiness and love. It felt extremely special for everyone.”

The partygoer added that it was Warren’s speech, which detailed his pride in his wife and their daughter, that made guests especially emotional.

Before the reception took place, a source said that it would likely be “very romantic” and that tents were already up a day before the event.

“Jessica is so excited,” the source told Us before the event. “This is such a happy time in their lives.” Adding to their excitement was daughter, Honor, 6 months, who joined the party wearing a gray dress — designed to exactly match Alba’s — with angel wings attached.

The pair exchanged vows for the first time on May 19 in the Beverly Hills courthouse’s ceremony room. The couple had gotten engaged after announcing that Alba was pregnant with their daughter.

“She doesn’t want to be pregnant in a dress,” a source told Us back in December 2007, which might have explained the couple’s privacy with the initial wedding.

Alba, 27, and Warren, 29, met on the set of Fantastic Four in 2004 (Warren was the assistant to the film’s director).

Yesterday’s reception took place at their newly remodeled $4 million Beverly Hills home.

“It’s a lot of stress to buy a house, have a baby and get married in six months,” she has said. “It’s a lot of life-changing decisions. I’m really, really secure and happy in my relationship.”
