Jillian Michaels is alleging The Biggest Loser producers' claim that she broke the rules by giving her team members caffeine pills was just an excuse to bring previously eliminated celebrity contestant Ruben Studdard back.

"You're spot on," Michaels replied Tuesday night to a Twitter follower who suggested The Biggest Loser trainer was "used by the show for a reason to bring a famous contestant back."

During Tuesday night's show, The Biggest Loser host Alison Sweeney revealed Michaels had previously given her White Team caffeine pills without the doctor's permission, which is a violation of show's rules and might've given her contestants a weight advantage at last week's weigh-in.

As a result, Michaels' four players were each given a one-pound disadvantage on the scale this week, Bob Harper's Blue Team received immunity, and more significantly, Studdard was allowed to re-enter the competition since the pill incident apparently occurred before the weigh-in that resulted in his elimination.

"I stand by my opinion," Michaels insisted during last night's broadcast. "A caffeine supplement is significantly healthier than unlimited amounts of coffee. My only regret is that my team, they are the ones suffering the consequences of my professional opinion."

The White Team ended up losing Tuesday night's weigh-in and contestant Craig Arrington was ousted. However, the team's four-pound disadvantage did not make a difference in the outcome -- with or without the penalty, they still would've lost.

Studdard won American Idol's second season and is the first celebrity contestant to compete on The Biggest Loser, which is currently in its fifteenth season. He was eliminated during last week's The Biggest Loser episode after his Red Team lost the weigh-in and he posted the lowest weight-loss percentage of anyone on his team.
