The 37-year-old model married the 62-year-old music producer on Saturday in an intimate ceremony held on Malibu beach near their home. The bride and groom went barefoot on their big day, with Ross donning a satin bias cut dress. A funny moment occurred when a skywriting plane spelled out "J heart M" instead "J heart L." Ross found the mistake very amusing and the plane later corrected itself.
While there were only about 50 guests invited to the wedding, there were over 300 people at their wedding reception on Sunday at David Geffen's house. Guests included Gwen Stefani, Eminem, will.i.am, Brian Grazer, Sir Paul McCartney, Scooter Braun, Alicia Keys, Swizz Beatz, Ellen DeGeneres and Portia de Rossi. Lady Gaga attended with her fiance, Taylor Kinney, and performed at the event with Tony Bennett. Mary J. Blige also sang for the happy couple.
Other famous guests at the party included Oprah Winfrey and Stedman Graham, who showed up with the TV star's best friend, Gayle King. Pharrell Williams and his wife, Helen Lasichanh, were also at there, along with Tom Hanks and his wife, Rita Wilson.
"Stepping out with my Valentine of almost 30 yrs! #iovinewedding," Oprah Instagrammed on Sunday.
"Valentine's Day wedding day for @jimmyiovine & @libertyross. Invite says red dress only!!" King also captioned a pic of her, Oprah and Stedman at the event.
Iovine's sons, Jamie and Jeremy, also posed for pics during their father's big day.
Ross and Iovine started dating in early 2013, following her very public split from ex-husband, Rupert Sanders. The Snow White and the Huntsmen director was caught cheating with the film's leading lady, Kristen Stewart, in July 2012. Ross filed for divorce from Sanders in January 2013, and it was finalized in July 2014. She got engaged to Iovine in September of last year.
Ross has two children from her marriage to Sanders, while Iovine has four children from his previous marriage to Vicki McCarty.
Iovine is the co-founder of Interscope Records and launched the headphone and streaming subscription service Beats Electronics with Dr. Dre. He has worked as an executive at Apple since the company bought Beats in 2014.
