According to TMZ, this is the second time Pitt, 55 has attended the weekly concert.
In the pictures shared to Instagram, Brad is wearing his signature cap and sunglasses combo, paired with a khaki-coloured t-shirt and relaxed, sand-coloured pants.
Just days before, Brad had appeared at the Venice Film Festival to support his new film Ad Astra.
Also in attendance at the concert were Kardashian family members Kim, Khloe, Kourteny and Kendall.
In addition, L.A. Reid, Adrienne Bailon and Big Boy made appearances at the church service - which Kanye has been taking around the country recently.
