OTRC: Steve Nicks: From 'American Idol' to 'Up All Night,' then 2012 tour

Stevie Nicks talks to OnTheRedCarpet.com in August 2011 during a satellite interview.

Steve Nicks appeared as the latest celebrity guest mentor on "American Idol" on Wednesday night's episode and is also set to guest star on the NBC comedy "Up All Night."

The 63-year-old legendary Fleetwood Mac singer has spent almost a year promoting her 2011 solo album, "In Your Dreams" with a slew of guest appearances on television and concerts. She toured with Rod Stewart last year and recently announced that the two will reunite for more concerts this summer.

On "American Idol," Nicks gave the remaining nine finalists pointers about their singing and also sang part of her group's 1977 hit "Dreams" with contestant Elise Testone. Nicks said: "If I needed a singer, I'd hire her in a second."

Testone earned the episode's fifth and final standing ovation from judges Randy Jackson, Jennifer Lopez and Steven Tyler for her show-closing performance of Led Zeppelin's "Whole Lotta Love." She and fellow rockers Colton Dixon and Philip Phillips also sang a medley of songs by Nicks and Fleetwood Mac.

Nicks had once said in a message posted on her official website that she thinks the FOX series is "very funny" and that if she were a judge, she "would be Simon Cowell." The acerbic British record mogul left the show in 2010 to launch another singing contest show, "The X Factor," on FOX.

In 2011, Nicks appeared on the Australian version of "The X Factor" and on "The Voice," NBC's breakout reality hit that stars Christina Aguilera, Cee Leo Green, Adam Levine and Blake Shelton. Nicks told OnTheRedCarpet.com at the season 1 finale of the latter singing contest series last year that if she were just starting her music career, she would most definitely participate in a reality talent show.

Nicks guest stars on "Up All Night" on an episode airing on Thursday, March 29. She plays herself. Christina Applegate and Maya Rudolph try to get her to appear on Rudolph's character's talk show in an exchange that sees the singer showcasing another talent - her ability to silence cranky babies and yappy dogs.

Nicks released "In Your Dreams" last May. It is her seventh studio album and first solo record in 10 years and includes songs inspired by the "Twilight" film saga and actress Reese Witherspoon. The singer told OnTheRedcarpet.com in August 2011, that she is working herself "to death" to bring new music to her fans.

"It's hard to sell records in this day and age, you know, unless you're Lady Gaga or unless you're in that youthful kind of dance performance artist thing, which is great, but then there's all the rest of us," Nicks said.
