Rihanna turned the Grammys stage into a big party last night with a highly energetic performance of her “We Found Love” single.

“Grammys, make some noise for Whitney!” Rihanna — dressed in all black — said to the crowd as she danced up a storm.

The tempo soon slowed, and the dancers took off, leaving Rihanna on-stage with just Chris Martin from Coldplay, who provided acoustic guitar accompaniment as the duo performed their collaboration song “Prince of China.”

Coldplay then finished the performance off by bringing the tempo back up and singing their hit song “Paradise.”

Rapper Jay-Z calls success suicide in his latest music release “Most Kingz” featuring singer/Coldplay front-man Chris Martin.

The track comes straight off Green Lantern‘s new Invasion Radio 2k10 mixtape…however the song isn’t exactly brand new itself. The vocals are from a Kingdom Come leftover that Jigga never found a beat for…guess it has a home now.

D/L: JAY-Z & CHRIS MARTIN – MOST KINGZ

R&B singer/songwriter Alicia Keys covered up her baby bump with this puffy, feathered dress as she arrived on the red carpet of the Keep A Child Alive Black Ball in London, England Thursday night (May 27). Alicia and her newly announced fiancee Swizz Beatz were joined by designer Christian Louboutin, actress Thandie Newton, musician Chris Martin, UK group JLS and more at the annual event, held to help raise awareness for Alicia’s charity.

Shortly after the event went down, it was announced that Alicia and Swizzy were not only engaged, but expecting a new baby. While we are still uncertain how far along Alicia is, her rep confirms that she is indeed pregnant and she and Swizz plan to tie the knot “in a private ceremony later this year.”

Over 83 million people tuned in last Friday night (Jan 22) to catch the Hope for Haiti Now telethon, which aired live and commercial-free on several major networks and was also streamed real-time online. The effort was spearheaded by MTV Networks, actor George Clooney and rapper/singer Wyclef Jean (who is from Haiti himself) in an effort to raise awareness and relief for the troubled country of Haiti, who suffered a massive earthquake earlier this month. According to recent numbers, over $61 million in pledges were made by members of the general public. Organizers will continue to take contributions for the next six months.

Celebrities who helped out by either performing or taking phone calls from pledges (or both) included Jay-Z, Rihanna, Bono from U2, Taylor Swift, Denzel Washington, Beyonce, Jennifer Hudson and tons more.

Jay-Z turned 40 last Friday (Dec 4) and celebrated the occasion with a really big (but VERY private) party in the Dominican Republic, thrown by his wife Beyonce and attended by big name celebrities like Mary J. Blige, Alicia Keys, Kanye West, Diddy, Ne-Yo, Oprah Winfrey, Lil Wayne and more. Troubled golfer Tiger Woods was also invited but was not in attendance due to his current situation with his wife and his 10 women.

Actresss Gwyneth Paltrow and Chris Martin from Coldplay were also missing from the crowd but sent a video message congratulating Jay-Z for seeing another year. The whole party itself was based off the Al Pacino movie “Scarface” and Beyonce and the rapper’s mom Gloria were the guests of honor.

Guests were chartered from New York via two private jets and were treated to a lavish dinner of canapés and caviar, along with Dom Perignon champagne to wash it all down. Kanye and Diddy performed and Alicia Keys sung an impromptu version of their hit single “Empire State of Mind.”

Fireworks were shot off at the ind of the night and was presented along with a 40s-style synchronized swimming display. But unfortunately you won’t be able to see any of this because no cameras were allowed and all guests were required to leave their personal cameras and mobile phones at the door to block people’s temptation of twitpicing little snippets of the shindig.
