The Montreal mixed martial arts star, who beat Carlos Condit two weeks ago to defend his welterweight title at UFC 154, tweeted a picture of himself in Paris on Friday.
"Thanks Tidiani Biga & Abdoulaye Fadiga for the great training session when I arrived in Paris this morning!" read the tweet.
The smiling St-Pierre appears to be healing well from his five-round war with Condit, with only a few marks left on his face.
St-Pierre went on vacation after his Bell Centre win. He tweeted Wednesday he was back in Montreal.
A super-fight with middleweight champion may be next for St-Pierre.
