C.T. Tamburello, one of the longest-running competitors on MTV's "The Challenge," is pulling the plug on his marriage.
C.T. beelined it to a Florida courthouse Monday and filed for divorce from Lilianet "Lili" Solares after more than 4 years of marriage.
It's unclear what led to the split ... but earlier this year C.T. revealed he was "in the doghouse" with Lili as he shot down rumors of a breakup.
There've been documented marriage issues ... back in 2020, C.T. said on an episode of "The Challenge: Double Agents" that he and Lili had separated the year before .
