T-Boz (search) of the female R&B group TLC (search) has filed for divorce from her husband, rapper Mack 10 (search), saying he committed adultery and threatened to kill her.

The singer — whose real name is Tionne Tenese Watkins Rolison — also has arranged for a temporary restraining order against the rapper, barring him from coming within 100 yards of her.

T-Boz filed the divorce papers and requested the restraining order June 8. She seeks full custody of their 3-year-old daughter, Chase Anela.

Mack 10, whose real name is Dedrick D-Mon Rolison, denied the allegations in court documents filed Friday. In them, he said his wife has made the claims "for the sole purpose of attempting to gain an advantage in these proceedings" and to prevent him from seeing their daughter.

The couple married in August 2000 and are now separated. T-Boz said in an affidavit that Mack 10 threatened to kill her several times, most recently on June 8.

The first threat allegedly occurred in October 2002. The 34-year-old singer said she was leaving Mack 10's home with Chase when the rapper grabbed their daughter from the car and told T-Boz she couldn't leave.

"My husband informed me that he would smash my teeth down my throat," she stated in the affidavit. "I asked my husband to give my daughter back to me and I reached for her, and my husband pushed me to the ground twice.

"At that point, my husband grabbed me around my neck and choked me," threatening to kill her, T-Boz said.

She said police officers had to help her and her daughter leave the home. Police reports on the incident weren't immediately available.

The violence continued, she said, when she told him in March 2003 that their marriage wasn't working. At that point, the affidavit states, Mack 10 threatened to have her "erased."

The 32-year-old rapper has been ordered to appear in court June 22.

TLC, whose hits include "Waterfalls," "Creep" and "No Scrubs," is one of the best-selling female groups of all time and has won four Grammys.

T-Boz and Rozonda "Chilli" Thomas have not released any new material since Lisa "Left-Eye" Lopes, the group's third member, died in a car crash in Honduras in April 2002.
