On Sunday, Gloria Gaynor, Jessie J and Arturo Sandoval performed at the 2015 Grammy Celebration at the Los Angeles Convention Center.

The event is also known as the official Grammy after-party. DJ Michelle Pesce was on the turntables in between performances. E! News was live broadcasting from the far corner of the party. We spotted personalities Terrence J, Khloé Kardashian, Christina Milian, Zanna Roberts Rassi chatting about the evening’s top moments. Kanye West and Kim Kardashian even stopped in to give Khloe an exclusive interview. The theme for the party was “Passport to the World” and it was truly stunning. There were hot air balloons, two train station platforms and a beautiful paddleboat in the center of the room.  We felt like we were in the ’20s and ’30s. Dancers, acrobats and aerialists entertained guests throughout the room. Celebrity caterer Along Came Mary designed a delectable menu that included five themed dinner stations (Victoria Station, Casablanca Airstrip, The Zeppelin, Transcontinental Railroad, and South Seas Steamship) and numerous destination-inspired desserts.

Soon it was time for the first act of the evening, the incomparable Jessie J. Earlier in the evening she performed with Tom Jones at the ceremony, but was excited to perform again. She kicked off her set with ”Ain’t Been Done.” Next up she performed “Sexy Lady.” The crowd went wild for “Domino.” Jessie is so great live and full of energy. She knows how to work the stage. She wore a black and silver sequined dress. She was accompanied by a guitarist, bass, keys and drums. She next performed “Seal Me With A Kiss” and “Sweet Talker” was another highlight.

In the MasterCard Jazz Lounge, Arturo Sandoval and members of the Grammy Camp — Jazz Session performed. This area of the party was more intimate and had a cool vibe. After party guests enjoyed Cîroc Ultra-Premium Vodka, Johnny Walker Black Label and Don Julio Tequila with beer by Anheuser-Busch. Beverages were also provided by Pepsi. Hyundai displayed its Hyundai Sonata Plug-In Hybrid vehicle at the bash, which was sponsored by Aflac, Degree Women,  Delta Air Lines, Hilton Hotels & Resorts, Hyundai, JBL, MasterCard, Microsoft Surface, People, Pepsi, Procter & Gamble (Covergirl, Crest, Herbal Essences, and Olay), and WestwoodOne.
