Updated Sunday, 9 a.m. PT: Deep in the heart of Texas, Matthew McConaughey said "I do." The "Magic Mike" star swapped vows with longtime girlfriend Camila Alves tonight in an intimate ceremony at their home in Austin, E! News has confirmed after first reporting that the wedding would take place this weekend.

Preparations were underway Friday, with a party-rental truck seen passing security outside the McConaughey compound, after which a van loaded with orchids also made the cut.

And no one had to worry about the guests being late--they spent the night!

The bride and groom's nearest and dearest had a pre-wedding slumber party last night, camping out in the several dozen or so two-person luxury tents erected in the back garden, each with its own air-conditioning unit, patio and doormat (gives it that homey touch, you know?) to accommodate the outdoorsy revelers.

A giant white tent was set up on the grounds, as well as six or seven long wooden dining tables, each one looking as if it could accommodate 15 to 20 people. Workers who helped set up were asked to sign nondisclosure agreements.

According to Entertainment Tonight, the theme of the wedding was "island beach meets Texas" with yellow and orange colors.

At the reception, guests reportedly enjoyed a variety of eats from Brazilian steakhouse Estancia Churrascaria, including Brazilian top and bottom steak, chicken wrapped in bacon and pork sausages with cheese bread.

While the guest list is being kept under wraps, we do know the identities of at least one adorable duo that was there: the bride and groom's nearly 4-year-old son, Levi, and 2-year-old daughter, Vida.

McConaughey and Alves, a Brazilian model turned handbag designer and TV host, met in 2007. He popped the question on Christmas Day.

The happy couple can just keep livin' together as always, albeit now as husband and wife.
