On Friday's live episode of The Oprah Winfrey Show, the singer said that she's happy to return to performing, and that singing at huge events such as the Super Bowl is "like therapy" for her.

"[I'm] in a very good place," the Oscar- and Grammy-winner, 27, told Winfrey. "I'm just glad to be back to work."

The highlight of Hudson's Grammy night on Feb. 8? Being handed her statuette by Whitney Houston, she says. "[That] almost surpassed" winning the award for best R&B album itself, she said. "I used to create duets with Whitney and myself."

She said her awards are in the piano room of her house, which she shares with her three dogs, named Oscar, Grammy and Dreamgirl.

The former American Idol contestant also sang her latest single, "If This Isn't Love," for the audience, but avoided talking about the murders last fall of her mother, brother and 7-year-old nephew in Chicago.
