Lady GaGa has showed fans that she is praying for Brazil following the tragic nightclub fire that claimed the lives of 231 people, including one of her biggest fans.

After retweeting a message informing her that a 'Little Monster' named Luiz Felipe had been killed, GaGa wrote: "My heart is with you Brazil.

"Sending my prayers to the families and friends who lost loved one in the fire in Brazil. Im thinking of you today during this tragedy...#prayforSantaMaria."

GaGa then posted a picture of herself with her eyes closed and palms together in prayer.

Demi Lovato, will.i.am, Axl Rose, Olivia Munn! and Taylor Momsen are among the other celebrities to have paid tributes to the victims of the fire.

Three people have reportedly been arrested over the inferno, which is believed to have begun when a band playing at Kiss lit a flare, igniting the ceiling.

An owner of the nightclub, a member of the band and its security chief are being questioned, while a fourth person - alleged to be a co-owner of the venue - is being sought by Brazilian police.
