Washington, August 13 : Ashton Kutcher has revealed that he has barely spent his millions earned from movies, fearing his career may come to an end any time.

The "What Happens in Vegas" star confessed that he does not splurge big bucks on extravagant purchases because he is worried his Hollywood days maybe numbered.

"You never know what happens in this business," Contactmusic quoted him as telling the New York Post.

"What we do for a living is nonsense. It''s entertainment... I still haven''t bought myself anything special with my earnings. I can''t even think what I''ve treated myself to.

"Actually, I haven''t spent anything. I''ve kept it all. Except I gave some to my stepdad, who drives needy kids wherever they have to go," he added. (ANI)
