Guests Thalia and Montana showed off snaps from inside the party on Instagram, sharing pictures of themselves alongside the birthday girl, who reportedly briefly took over for the DJ, and spent most of the night on the dance floor.

Other stars in attendance included British pop star Natasha Bedingfield and rapper Fat Joe, while Lopez’s longtime manager Benny Medina paid a special tribute to his friend by bringing out a large cake for Lopez and giving her a touching toast.
