It wasn’t easy for Teri Hatcher to get up on stage and perform Carrie Underwood’s “Before He Cheats” on Wednesday night’s Idol Gives Back special.

“Singing on Idol Gives Back … now that was nerve-wracking!” Hatcher told Usmagazine.com after taping her performance Sunday.

Her Desperate Housewives costar James Denton played the guitar.

“She’s brilliant,” he raved to Us. “She did Cabaret on Broadway — people forget that she’s a great singer!”

Hatcher said Denton had a hand in picking the song.

“Jamie texted me and said, ‘I just heard this song, and I think it would be great for you,’” she told Us.

“And not 10 minutes earlier, my daughter and I had heard it on the radio, and she said to me, ‘You’d be really good at this song!’” Hatcher added. “So I told Jamie, ‘It was really weird that my daughter said the same thing, so I guess that’s what we should sing.’”

After her performance, Underwood came out on stage and congratulated her.

Said Hatcher, “She was very sweet. I didn’t put her on the spot or anything!”
