Justin's Intimate Set
JT made his way to stage at The Palladium to entertain his fans around 11:35 p.m. How'd he start off the night? By rapping a verse of "Bands Make Her Dance" by Juicy J - and the crowd went wild! Then, of course, he moved on to his new tunes. "He was having a blast," a concert goer tells Life & Style. JT sang some of his big hits, including "Lovestoned" and "Senorita," - even apologizing to the crowd for taking such a long hiatus from music. After singing a beautiful version of "What Goes Around...Comes Around," he cues "Suit & Tie." Who joins him onstage? Jay-Z! "It seemed like they were really good friends and had great chemistry," the guest says. "Justin was concise, professional yet seemed whole-heartedly grateful to the fans for their attendance - it was awesome."
Warner Music Group Celebration
From Neil Patrick Harris and Lena Dunham to Blake Shelton and Miranda Lambert, this party was one of the hottest ones to attend! "Lena came with her boyfriend, Jack Antonoff, from fun.," an eyewitness tells Life & Style. "She walked into the party with her heels in her hand." The onlooker says they also spotted the Girls creator and star leaving the party and walking toward Sunset Boulevard, trying to find a pal. "She was making plans on her cell," the eyewitness notes. The 26-year-old was overheard telling the friend she was wearing a yellow dress and to look for her as she walked toward Sunset. Blake and Miranda stayed for about an hour before heading out. Miranda had a tough time with her heels, though - she was stumbling in them on the unevenly paved driveway as they made their way out! Neil Patrick Harris and partner, David Burtka, Sting and his wife, Trudie, Ellen Pompeo, Julia Stiles, Amy Smart, Wiz Khalifa and Dita Von Teese were also in attendance.
Monster's House of Hype
Who wouldn't want to hang with the likes of Ne-Yo, Swizz Beatz, and Alicia Keys? Alicia and her man looked so in love as they sat at a table with Ne-Yo. "Alicia was wearing white sweatpants and a black leather coat," an onlooker tells Life & Style. "She was talking with Swizz and taking pics, but only stayed for about five minute. Swizz moved to the DJ booth." A little after 1 a.m., Swizz yelled "T.I. and Pharrell in the building!" The crowd went absolutely wild!
After wowing on the red carpet, Katy Perry attended this after party with her beau, John. "They hung out together with a group of friends. She 'cheers'-ed to the group and smiled a lot," a party guest tells Life & Style.
Though Taylor Swift was supposed to attend this party, she never showed. But that's okay! There were tons of other celebs in sight. "Kelly Rowland was in this orange body-hugging floor length dress and was so happy," an eyewitness shares. "She left around 11 p.m." Grammy winner Gotye had a table and seemed very chilled out, while Akon sat with a huge entourage at his table.
Adam Levine's After Party at Soho House
Who wouldn't want to be at Adam's party? Questlove of The Roots held down the DJ booth while Pharrell had a table in the main room. Around midnight, the Maroon 5 front man arrived and dined on tons of appetizers with his band. "Adam spent about 30 minutes flirting with two attractive girls," a guest tells Life & Style. "Sting arrived and greeted Adam at his table. The two hugged, chatted, laughed and posed for pictures."
