Can you believe that this was the first time Cash Warren and Jessica Alba's families join each other to celebrate their wedding at the Beverly Hills home?

Believe it or not, the two families organised a weekend reception on Friday to "celebrate their love and commitment to each other", an insider told Usmagazine.

Roselyn Sanchez [the "Without a Trace" star] was reported to be one of the guests, guests which were asked to arrive before 7 p.m. 

The same partygoer stated that the two fathers expressed their happiness over the wedding, and that a mariachi band was there to cheer them up.

"There were no tears, just lots of happiness and love. It felt extremely special for everyone."

"This is such a happy time in their lives."

The reception was a real success, taking place at their $4 million Beverly Hills home.

"It's a lot of stress to buy a house, have a baby and get married in six months"

"It's a lot of life-changing decisions. I'm really, really secure and happy in my relationship." Jessica Alba said.
