Earlier today, Brandy and Monica reunited onstage to rehearse for the Pre-Grammy Gala honoring Sir Richard Branson. The ladies sounded just as good as they did 14 years ago while performing their Grammy-winning collaboration “The Boy Is Mine” and new song “It All Belongs to Me,” backed by a live band. Whitney Houston even stopped by the Beverly Hilton ballroom to support the girls for their big performance on Saturday. (Excuse the low-quality pics.)

Kelly Rowland glowed in an orange gown while catching up with her fellow Destiny’s Child diva Michelle Williams at the 3rd annual ESSENCE Black Women in Music event held during Grammy Week. The “Motivation” singer and music industry veteran Sylvia Rhone were honored as movers and shakers.

MC Lyte played DJ and Kelly hit the stage, performing her smash single “Motivation” and reuniting with Eve for their 2007 collaboration “Like This.” Kelly, who is nominated at this weekend’s Grammys, was presented with a platinum plaque by “Motivation” hitmaker Rico Love.

Other attendees included LeToya Luckett, Ne-Yo, Dawn Richard, Melody Thornton, and Melanie Amaro.

Grammy Week was in full swing as music’s brightest stars came out to honor Interscope chairman Jimmy Iovine at the 54th Annual Grammy Awards Producers & Engineers Wing event at the Village in Los Angeles. From Dr. Dre to Stevie Nicks, the room was full of artists of all genres. Skylar Grey kicked off the evening with a medley of her hits and Mary J. Blige, will.i.am, and Polow Da Don were among those who saluted the music visionary.

Nicki Minaj wilds out in a second hilarious promo for the 54th Annual Grammy Awards on CBS. The blonde diva raps and shakes her booty as Grammy host LL Cool J beatboxes, but when he can’t keep up, she tells him to “pause.”

Nicki will debut “Roman Holiday,” a new song off her sophomore album Pink Friday: Roman Reloaded, at Sunday’s show, where she is nominated four times.

The Grammy telecast is adding even more star power in the days leading up to Sunday’s show. Alicia Keys will honor the late legend Etta James with a special performance.

The 14-time Grammy winner will team with blues icon Bonnie Raitt for a tribute at the 54th annual event, airing live from the Staples Center in Los Angeles on February 12.

The “At Last” singer died last month at the age of 73 from complications from leukemia. “Wow Etta James! :-( What a phenomenal woman and spectacular voice!” tweeted Alicia upon learning of her passing.

Other performers at this year’s Grammys include Chris Brown, Nicki Minaj, Bruno Mars, Adele, Taylor Swift, Katy Perry, Kelly Clarkson, and more.

Brandy and Monica delighted their fans by debuting their new single “It All Belongs to Me” on Monday. And now the R&B divas will team up to perform the song live at the Pre-Grammy Gala in Beverly Hills this weekend.

Rap-Up.com has learned that the singers will take the stage at the star-studded affair, considered the highlight of Grammy weekend. This year’s event, hosted by Clive Davis, will honor Sir Richard Branson and feature other surprise musical guests. Past performers include Whitney Houston, Jennifer Hudson, and Alicia Keys.

Brandy and Monica will shoot a video for the Rico Love-produced song on February 13 with director Chris Robinson, and perform it on “The Tonight Show with Jay Leno” the same week.

“It’s just great to come back and do something with [Monica],” Brandy said during an interview on Atlanta’s V-103. “This is definitely a blessing.”

Three years ago on the eve of the Grammys, Chris Brown’s career nearly ended after his infamous fight with Rihanna. But this Sunday, the singer will make a triumphant return to the stage.

Brown has been officially announced as a performer at the 54th Annual Grammy Awards, where he is nominated in three categories including Best R&B Album for F.A.M.E.

The night before the Grammys in 2009, the R&B star and his then-girlfriend got into an altercation while leaving Clive Davis’ pre-Grammy party. They both pulled out of their appearances at the show the next day.

Brown experienced a fallout from the incident, but has managed to bounce back with hit singles and albums. This will mark his first time on the Grammy stage since 2008 and the first time the former couple has attended the same awards show since that fateful night.

Rihanna is also set to hit the stage on music’s biggest night. The pop star, who is nominated for four awards including Album of the Year for Loud, will join Coldplay on their collaboration “Princess of China.”

The 54th Annual Grammy Awards will air live from Los Angeles’ Staples Center on February 12. Other performers include Nicki Minaj, Bruno Mars, Adele, Taylor Swift, Katy Perry, Kelly Clarkson, and more.

J. Cole will be looking his best when he heads to the Grammys next weekend. The Roc Nation rapper, who will compete for Best New Artist against Nicki Minaj, The Band Perry, Bon Iver, and Skrillex, spoke to USA Today about his nomination for his debut Cole World: The Sideline Story, and where he was when he first received the good news.

“I’m very happy just to be nominated. If I don’t win, it’s OK,” said a humble Cole. “Now don’t get me wrong, I would love to win.”

He already has his outfit picked out. “I’m going to be looking very nice in a good suit,” he said. “I’m going to bring my family and friends and celebrate. I don’t know how likely it is that I’ll win, but I’ve learned that anything is possible.”

J. Cole and Nicki Minaj will compete for Best New Artist at the 54th Annual Grammy Awards on February 12. The superstar rappers shared their journey to the Grammys in a video series presented by Pepsi and Pandora.

Before the “Work Out” MC was signed to Roc Nation, he was a college kid trying to get his CD in Jay-Z’s hands. He describes moving to the big city and being rejected by Jay the first time they met.

“Being the first artist signed to Roc Nation, there’s a lot of pressure that rides on it, a lot of expectations,” said the North Carolina native. “That’s how I work, I work off motivation. I’m about to really kill the game ’cause I’m prepared.”

Four-time nominee Nicki, who will perform at this year’s show, is just happy to be nominated. “I’m not going to be nervous about winning ’cause I really don’t think I’m gonna win anything,” said the pink-haired diva. “I know eventually in my career I’m gonna have Grammys. This year is just about being nominated and feeling grateful.”

Taylor Swift and LL Cool J let loose in a promo for the 54th Annual Grammy Awards. The hip-hop pioneer, who will host this year’s show, kicks things off before the country sweetheart joins in with her own sound effects. It’s not long before their beatboxing session erupts into laughter. Expect more unexpected pairings like this when the Grammys air live on February 12.
