Tichina Arnold announced her split from husband Rico Hines in 2016 and filed for divorce last August

According to court documents obtained by PEOPLE, the Martin alum, 53, finalized her divorce from estranged husband Rico Hines on July 15

Arnold, who represented herself, filed for divorce last August and cited "irreconcilable differences" after her rep confirmed their split to PEOPLE in Jan. 2016

The Everybody Hates Chris actress later told PEOPLE that she announced their breakup to "very close people" by texting out a sex tape of Hines

"I did not expect it to go public the way it did," Arnold said in July 2016, insisting that "no one from my side leaked it" after the incriminating video got out.

"It's beyond the fact that the infidelity, it happens. We make mistakes," she said. "And we fixed a few mistakes of his prior infidelities."

Arnold later told PEOPLE that she didn't know "how to be single again" as she opened up about getting back to the dating scene

Before Arnold wed Hines in an intimate Honolulu ceremony in August 2012, she was married to heavyweight boxing star Lamon Brewster
