Kamala Harris speaks onstage during the The Human Rights Campaign 2019 Los Angeles Gala Dinner at JW Marriott Los Angeles at L.A. LIVE on March 30, 2019 in Los Angeles.

Scooter Braun and wife Yael hosted a fundraiser for presidential candidate Sen. Kamala Harris on Saturday (July 20) at their California home. The event, advertised as a "fireside chat" with the California Democrat, included appearances from Braun's superstar clients, Ariana Grande and Demi Lovato, as well as Katy Perry, based on pictures of the gathering posted by Braun and Harris.

The 54 year-old junior senator, who made a splash last month at the first Democratic debate during a back-and-forth with former Vice President Joe Biden over school busing, captioned her picture with the singers with the caption "tag the fierce women in your life," while Braun wrote simply, "fam" while posing with Grande and Lovato.

As the nearly two dozen democratic candidates scramble to raise money, the Harris gathering wasn't the only superstar political summit on Saturday night in California. Harris' rival, New Jersey Sen. Cory Booker had his own event at a private residence in Santa Monica with a guest list that included Sophia Bush, Tiffany Haddish, Matthew Modine, Lea Thompson, Rosario Dawson and Ed Begley Jr., among others.
