Celebrities flocked to David Geffen's California home on Sunday to watch Liberty Ross and Jimmy Iovine tie the knot in a special Valentine's Day wedding. A source tells PEOPLE that guests were escorted to the venue by a private driver and all the women were asked to wear red.
Another source notes that there were roughly 300 guests in attendance as the British model, 37, wed the Interscope Records founder, 62.
Famous well-wishers included Tom Hanks and Oprah Winfrey, who shared a snap on Instagram ahead of the wedding in a red dress.
"Stepping out with my Valentine of almost 30 yrs! #iovinewedding," she wrote alongside a photo with longtime partner Stedman Graham.
Pharrell Williams also shared a photo from the wedding with his wife Helen Lasichanh dressed in red.
Iovine's sons, Jamie and Jeremy, shared a snap before the wedding as they posed in stylish suits.
"Me and Jeremy ready for the wedding," Jamie, who wore a red suit, wrote. He also shared a photo of himself with Lady Gaga.

On Saturday, the couple hosted a small family luncheon ahead of their nuptials.
The British model accepted Iovine's proposal in September – over two years after she filed for divorce from her director husband Rupert Sanders.
Her decision to divorce after 10 years of marriage, came on the hills of a cheating scandal when Sanders, 44, was photographed hugging and kissing actress Kristen Stewart, then 24, whom he directed in Snow White and the Huntsman.
After the pair split, Ross's brother – Oscar-winning composer Atticus Ross – contacted record executive and American Idol mentor Iovine, who provided support to Ross before the two began dating.
