Joe Jonas, 24, and his model girlfriend Blanda Eggenschwiler were also among the fashionable guests at the Dream for Future Africa gala at Spago honoring Vogue Italia editor-in-chief Franca Sozzani.
Joe and Eggenschwiler were the last to hit the swanky affair. They posed arm-in-arm for photographers but skipped talking to the media gathered along the red carpet.
Once inside Spago, the two chatted with Sozzani's photographer-director son, Francesco Carrozzini.
Their table included fellow celebs Chord Overstreet, Alex Pettyfer and designer Rachel Roy.
Earlier in the week, Joe and Eggenschwiler were spotted shopping at Fred Segal in West Hollywood.
A few nights before, Joe was also at another fashion event in Beverly Hills, the Ferragamo-hosted opening of the Wallis Annenberg Center for the Performing Arts. He shared a long chat wit his ex, Camilla Belle, before taking a seat at his table next to Lori Loughlin.
The Jonas Brothers announced earlier this month that they canceled their highly anticipated tour due to problems among the three artists. "There is a deep rift within the band," their rep told E! News. "There was a big disagreement over their music direction."
