The bride's wedding gown was designed by Elie Saab, while Oscar-winning costume designer Ngila Dickson (The Lord of the Rings) created the groom's attire.

In March, Parker revealed on Twitter that Dickson was "creating gorgeous, inspiring, and unique designs that are both modern and whimsical."

He also denied a report that the wedding would have a medieval theme.

"Sorry to disappoint, but the wardrobe we're giving wedding guests is essentially modern. No swords or chain mail," he wrote. "Just because we don't trust our guests to dress themselves properly doesn't mean we want them to look like # GoT  characters. This is not a 'theme' wedding, and there will be nothing medieval about it."

Meanwhile, wedding guests treated to musical performances by Loreena McKennit and The Good, The Bad & The Ginger and a cake by Napa Valley's Perfect Endings.

Parker and Lenas became engaged in April 2011. They have a 5-month-old daughter, Winter.

Parker helped start the music-sharing site Napster and was an early Facebook adviser who served as its first president. He was portrayed as a hard-partying ladies man by Justin Timberlake in the movie The Social Network. Parker has denied any similarities -- other than the name -- between himself and the character, calling the movie's Sean Parker "a morally reprehensible human being" and a "complete work of fiction."

Parker is currently backing the music-streaming service Spotify and been involved with the Founders Fund, a venture capital firm based in San Francisco. Forbes estimates his net worth at $2 billion.
