Nikki Sixx unfollowed Tommy Lee on Twitter the day after Motley Crue's final gig.
The group went their separate ways on New Year's Eve (31.12.15) and the 53-year-old drummer admits he hasn't heard from his bandmates since.
Tommy said: "I think f***ing Nikki unfollowed me on fucking Twitter, like, the next day. I was like, 'Wow. OK, dude.' "
And Tommy admitted he has always had "issues" with the 57-year-old bassist.
He told Rolling Stone magazine: "There's always been issues."
And despite being together for over 30 years, the group - which also included Vince Neil and Mick Mars - didn't even say a formal goodbye when they came off stage at Los Angeles' Staples Centre for the final time.
Tommy said: "After the final night, we had a big party backstage on New Year's Eve, and I never saw the other guys. We never even said 'goodbye'.
"F***ing strange as hell, dude. I mean, what the f**k?
"I really don't know. I mean, if you're getting divorced, you still give your ex a hug, or flip her off or something. You either get a kiss or a slap, or ... something. Give me a sign! Let me know you're alive."
The 'Girls Girls Girls' group never had any pre-show rituals because they didn't see one another until they were on stage.
The drummer said: "We just see each other up onstage and let it rip. It's kind of strange, man. We're a f***ing weird band."
Despite the apparent tensions, Tommy has no regrets about his years in the band.
He said: "I don't have ill feelings at all. I'm saying this with a smile on my face. I'm just happy to be part of something that was so impactful on so many people's lives musically and lifestyle-wise.
"That's pretty f***ing insane, and I'm really happy that we decided to end it on a high note and not really drive this thing into the ground like so many of our other musical peers have.
"It's just really cool and quite an honour to kind of bow out when it's still larger-than-life. It could have gone a different route."
