Back in 2011, Eminem, Rihanna, Dr. Dre, Skylar Grey and Adam Levine performed “Love The Way You Lie (Part 2)” and “I Need A Doctor” at the 53rd annual Grammy awards.

Couple of days ago, Skylar Grey revealed that she was not satisfied by her performance and Eminem gave her a big kiss to calm her down. Skylar shared a short video of the show on Instagram with the caption:

“The most surreal moment in my life as a performer,” she said “I dreamed about being on that stage since childhood. After we got off stage, Em gave me a big kiss on the cheek and seemed very pleased with the performance. However, I locked myself in my dressing room and cried because I thought I did not sing good! Will forever be hard on myself but I guess that is what keeps me reaching…”

It’s not the first time the singer recalls the surreal moment of her career. In the Genius annotation, Skylar Grey wrote: “The most amazing thing for me with this was getting to perform at the Grammys with Dr. Dre and Eminem (‘I Need A Doctor’) when Rihanna opened up our medley with ‘Love The Way You Lie.’ That was a really special moment in my life.”

“I Need A Doctor” is a cinematic song detailing the relationship between Eminem and Dr. Dre. The song is produced by Alex da Kid and was supposed to be included in mystical Dre album, DETOX. In the song, Em raps about Dre being stuck creatively, unable to make music the way he used to due to his grief and depression. Em, who went through this himself after his best friend died in 2006, is making a passionate attempt to get through to him so Dre will start believing in his own abilities again.

That night at the Grammys, Eminem had most nominations than any artist and won Best Rap Solo Performance for “Not Afraid,” beating “Over” by Drake, “How Low” by Ludacris, “I’m Back” by T.I. and “Power” by Kanye West and Best Rap Album for Recovery, besting The Adventures Of Bobby Ray by B.o.B., “Thank Me Later” by Drake, “The Blueprint 3” by Jay-Z and “How I Got Over” by The Roots.
