SHOW BLITZ: Tabby is using up his lives.
WONDERING why X-Factor star Tabby Callaghan has been so quiet lately?
The singer has been touring the UK with his band The Tsars and according to one insider the Sligo rocker has been working so hard friends and family fear exhaustion could be looming.
One close pal said: "Tabby is such a hard worker, he's lives and breathes his job. He has been travelling all over the place lately and it's becoming a real strain.
"The good thing is he's looking forward to the release of the new single Take A Swing this month and once promotion for that is over he can have a few weeks break in the summer."
