Lady Gaga paid a special tribute to her beloved grandfather, who died last month (22Sep10), during a concert in Finland on Wednesday (13Oct10).

The Poker Face hitmaker was devastated when Joseph 'Giuseppe' Germanotta passed away at the age of 88, just two days after she visited him at his New Jersey nursing home.

Gaga halted her gig in Helsinki on Wednesday to honour her grandfather, dedicating her ballad Speechless to him.

She told the crowd, "My dad made me promise that tonight I would dedicate this song to my sweet, sweet grandpa who is in heaven.

"My grandpa was a real p**ser, I'll tell you. He was something else. He liked things to be exactly how he wanted them... This is for my good, sweet grandpa and to any loved ones you may have lost. This song's called Speechless."
