She was sure that her country, France, would not make it to the World Cup in Brazil next year.
France was trailing 0-2 after the first leg qualifiers against Ukraine.
So Miss Doria Tillier, 27, boldly promised to strip if France managed to qualify. Unfortunately for the weather presenter of the Canal+ channel, France made a remarkable comeback, winning 3-2 on aggregate.
Predictably, the ratings went through the roof as millions of the channel's viewers wanted to see Miss Tillier keeping her word, the Mail Online reported.
She did, although not in the way viewers may have expected.
Instead of taking off her clothes on screen, she made a series of jokes and allowed a long distance back shot of her running across a field.
She said she would be "a poil" - French for naked - but she actually presented the weather from Poil, which is a village near Paris, The Huffington Post reported.
"It was a pathetic stunt, not funny at all," said disappointed viewer Remy Jacob.
"Everyone was hoping Doria would be a good sport, but it was all nonsense."
Miss Tillier, a former model and actress, has been presenting the weather on the nightly news and talk show since August last year.
After France scored their second goal to draw level on Tuesday, she had tweeted: "2-0 for France. I'm starting to stress."
But on Wednesday night, she looked calm and relaxed, and had a big smile on her face as she forecast the weather from Poil. Meanwhile, another presenter, Mr Antoine de Caunes, 60, had to carry out most of his Grand Journal programme in English as his forfeit as he, too, failed to predict the France result.
He said: "Some of you will see us as patriots, some of you will see us as idiots. Frankly I don't...care. France have qualified."
France last won the World Cup in 1998 and were runners-up in 2006.
