Ex Goo Goo Dolls Drummer -- I Got Booted for Having a Baby

The Goo Goo Dolls' ex-drummer has major beef with the band because he says he got 86'd just because he wanted to be with his wife when she was giving birth to their twins.

Michael Malinin filed a Federal lawsuit against frontman Johnny Rzeznik and bassist Robert Takac ... over his firing from the group in December 2013. According to the suit, the Dolls were on a tour when Malinin got word his wife was about to pop.

He says his paternity leave had been discussed in advance, and everyone knew he would have to leave for a few weeks around the birth. But Malinin says when the time came ... the band manager told him he was getting canned.

In the suit, MM says he was told specifically that Johnny wanted him gone. He says they didn't even give him a severance package for his 19 years of Goo Goo service.

Malinin says he'd been getting a third of the 3-man band's profits ... so, he's suing to get back a chunk of that cash.

And now ... some of Malinin's finest work.
