“I entered boxing saying I wanted to be an undefeated world champion. So to fight [Suzy Taylor] for the first time and take that belt, by stopping her in the second round, was amazing,” the 39-year-old athlete told Closer at the Third Annual Sports Humanitarian Awards in July.

Laila took home her first championship title 15 years ago during the IBA Super Middleweight Championship match in Las Vegas. “I didn’t want to let the belt go — and I never did!” she told Closer of holding on to her coveted award.

Throughout her career, Laila won the WBC, WIBA, IWBF, and IBA female super middleweight titles, and the IWBF light heavyweight title.
