"I'm happy to confirm that Carrie Underwood is engaged to Mike Fisher, and the couple couldn't be happier," her rep tells PEOPLE. "No wedding date has been set at this time."
The Ottawa Senators player spoke about the happy event on Monday, according to the Toronto Sun.
"It's true," he is quoted as saying. "We're both obviously excited and very happy."
Fisher, 29, reportedly proposed at his home Sunday afternoon and then sent messages to his friends with the good news later that day.
Underwood, 26, and Fisher have kept their year-long relationship mostly under the radar, but Underwood declared her love for Fisher in the liner notes of her new album, Play On.
"I love you so much!" she wrote. "You make my life better in every way! I thank God for you every day."
Carrie Underwood Flashes Engagement Ring Tuesday – December 22, 2009 – 8:54am
Carrie Underwood flashed her new diamond engagement ring Monday night as her fiance Mike Fisher's Ottawa Senators hockey team faced off against the Boston Bruins in Ottawa.
Despite his team's 2-0 loss, he was all smiles as he spoke to reporters.
"It's true. We’re both obviously excited and very happy," Fisher, 29, said when asked about the engagement. "I'm not sure exactly when (the wedding will take place)." His website said they hope to wed sometime next summer.
He declined a question asking if he was on bended knee when he popped the question Sunday.
"That's all I’m going to say: We're both very happy and excited," he said.
His teammates couldn't be more thrilled for him. "It's great. It's a long time coming," said Winger Chris Neil. "There's going to be a lot of broken hearts here in Ottawa with all those girls that are in love with Mikey."
But he said Underwood, 26, is "an awesome girl. We're ecstatic for him."
