Katy Perry treated 21 of her tour crew to a spa visit.

The group took over the entire Remede Spa at the St. Regis Hotel in Atlanta on June 8 following her concert in the city, and the 'Firework' hitmaker footed the bill for facials and treatments.

Among the treats were a 90 minute facial at $255 and aromatherapy massages at $240 for over an hour.

They were also given warm paraffin foot wraps, foot and scalp rubs and eye and lip treatments, according to US Weekly.

The 26-year-old singer - who is married to British comedian Russell Brand - recently revealed she and her tour crew like to pray before they go on stage, and always dedicate the show to someone or something.

She said: "I have this little box of prayers, but they're very small, simple one-line prayers, and I pull them out and read them out loud, and everybody either agrees or disagrees with them, and then we put our hands in a pile and dedicate the show to something funny or stupid."
