Mika spent his Christmas in hospital looking after his sister.
The 'Love Today' singer and his family stayed with his sister Paloma Penniman - who has been in a London hospital since October when she fell 50 feet out of a window and became impaled on railings - even putting the recording of his third album in the US on hold to be with her.
Speaking of the incident for the first time, he told the Daily Star newspaper: "At the end of last year I was going back and forth between Paloma and the recording studio in America.
"Christmas was a bit different this year, we didn't want to leave my sister on her own so all of my family were in hospital on Christmas Day and we've been with her every day over the holidays.
"We tried to make it all fun for her but it has been awful, such a shock, and we don't know when she will leave. It is still pretty serious."
Paloma, 28, was impaled through her legs in the horrific accident, and Mika, 27, has previously praised the helicopter team and medical staff at the Royal London Hospital in London for their efforts in saving her and thanked fans for their well wishes.
He previously wrote on his official website: "On behalf of my whole family, we would like to thank everyone for their thoughts and kindness over the past week.
"We are eternally grateful to the helicopter response unit, doctors and nurses of the Royal London for saving her life.
"Every card, text message and bunch of flowers has been shown to Paloma. We are extremely grateful to you all for keeping Paloma in your thoughts and prayers."
Mika is planning to release the follow up to his album 'The Boy Who Knew Too Little' this year.
