After the Internet was buzzing over rumors that tennis star Anna Kournikova would be replacing Jillian Michaels on The Biggest Loser, Kournikova made her first appearance as a trainer on Tuesday's finale.
Kournikova's full-time gig is not her first time on the Biggest Loser ranch. In 2010, she coached contestants in a tennis-themed challenge.
The sexy athlete -- and longtime love to Enrique Iglesias -- already hinted at her fitness philosophy.
"Mind is a powerful thing. You can make things happen if you want them bad enough," she said. "I know all about discipline, strength and conditioning, commitment. This is my chance to give back -- the opportunity of a lifetime -- and a way to teach the contestants everything I know."
For her part, departing trainer Michaels, 37, who is leaving to focus on starting a family, is grateful for her stint on the series.
"It's been such an honor working side by side with you guys and I'm eternally grateful," said Michaels, who will soon assume a cohost role on syndicated medical series The Doctors. "Now, I'm just excited for new chapters, to take the platform I've been given to the next level."
