The Grammy Awards are coming up Sunday (February 9) and it will be their milestone 50th ceremony.

The stop artists expected to take home several trophies are Kanye West and Amy Winehouse. While Kanye has been added on as a performer, Winehouse recently revealed that she will not be attending, but apologized.

“I’m really sorry I can’t be there but I appreciate that I’m being given a second chance via satellite,” Winehouse said in a statement.

Both artists are the top runners in numerous categories. West leads the pack with eight nominations including Album of the Year for Gradation, which spawned the hit singles “Can’t Tell Me Nothing” and “Good Life” both of which are up for noms as well.

Winehouse is also a leading candidate garnering noms in six categories including Best New Artist and Record of the Year for her smash hit “Rehab.”

Winehouse has been in the news lately as media speculated whether or not she’d attend. After a stint in rehab and her application for a visa to enter the country, she decided not to come, although her visa was approved.

In addition to a performance by West, Beyonce is scheduled to perform alongside Tina Turner, while Fergie has been tapped for a duet with John Legend. Lastly, Rihanna — whose hit “Umbrella” is up for a few Grammy’s — will take the stage with pop-funk band The Time.

Following the nominee leaders are Ne-Yo, Jay-Z, Timbaland, Justin Timberlake and T-Pain — all of which are nominated with five each.

R&B singer Tank is also up for two awards — for the first time in his career — for his 2007 release Sex, Love & Pain. He celebrated the career first with a pre-Grammy party on Thursday (February 7) where he expressed his excitement and confidence in winning.

“It’s an opportunity of a lifetime for my first time to be a Grammy nomination… to be two of them at that,” the singer told Thursday. “So, we going to get our hardware baby. We going to get it. We praying and believing that that’s ours.”

The 50th Annual Grammy Awards will broadcast live from Staples Center in Los Angeles on Sunday at 8 p.m. EST on CBS.
