Idina Menzel's performance of "Let It Go" on ABC's "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest" was slammed by critics because she botched the "Frozen" classic, reports ABC News.

The normally pitch-perfect Menzel flubbed the high note during the song's climax.

The Tony Award-Winning singer and actress, 43, responded to critics on New Year's Day by posting an image on Twitter of an interview she gave last year in which she defined success.

"There are about 3 million notes in a two-and-a-half-hour musical," she said in the interview. "Being a perfectionist, it took me a long time to realize that if I'm hitting 75 percent of them, I'm succeeding."

The interview appeared in November's issue of Southwest magazine. It also included Menzel's advice of "staying in the moment" and "connecting with the audience in an authentic way" during a show.

"I am more than the notes I hit, and that's how I try to approach my life," she said.

Menzel also said, although it is not possible to get it right all the time, you simply try your best. After that, "All that's left is to accept your shortcomings and have the courage to try to overcome them."

The "Holiday Wishes" singer performed during the CMA 2014 Country Christmas on Nov. 7 in Nashville, Tennessee, without missing a note.

When Menzel is not defending her New Year's Eve performance, she is headlining a Tony-nominated Broadway show "If/Then" and caring for her 5-year-old son, Walker Nathaniel Diggs.

"The guilt is the thing that we as women all feel, whether we stay at home or we work. There are a lot of double standards with the way the men in our lives see how we make those choices," she told Redbook magazine. "I think there's an accounting for how much time I spend with my son, and men don't have to account for how much time they spend with their child. It hurts to feel that's a judgment being made. Because we're already judging ourselves."

When Redbook asked Menzel about dating following her divorce from husband Taye Diggs, the singer said, "I'm open to it. I just don't have a lot of time. They'd have to meet me at, like, midnight after the show, and that's kind of slutty, isn't it?"
