The legendary 'Girls Girls Girls' rockers recently booked a Las Vegas residency for next February, but the 50-year-old singer admitted he is considering his future with the band after the run of shows.
He said: "It's not definite, but I am thinking seriously about it.
"This is all about me thinking about the second half of my life, thinking about my future, and that future might not include Motley Crue after Vegas."
The rocker admitted having time to reflect while holidaying in the Bahamas following the end of a year-long 30th anniversary tour is making him seriously consider what he wants to do with his life.
He added to the Las Vegas Sun newspaper: "I'm sitting on my yacht, contemplating my future, and I'm not sure it will be with Motley Crue after Las Vegas. Great things are coming up and pushing me in another direction.
"It's been a great ride, and I've enjoyed every second of it, but being out here relaxing in this beautiful place has given me the chance to reflect on what direction I want the rest of my life to take. I'm really giving it a lot of thought."
