Beyonce Couples Up With Chris Martin on 'Hope for Haiti'

Beyonce Knowles has lent her powerful voice for "Hope for Haiti Now: A Global Benefit for Earthquake Relief" telethon on Friday, January 22. Taking part in the two-hour benefit event, the "If I Were a Boy" hitmaker delivered single "Halo" with the companion of piano play by Chris Martin, the lead vocalist of Coldplay.

On the special performance, the 28-year-old songstress also managed to inject Haiti into the lyrics of her fourth single off "I Am...Sasha Fierce". "Haiti, we can see your halo/ You know you're my saving grace," she sang. "You're everything I need and more, it's written all over your face/ Haiti, we can see your halo/ I pray you won't fade away."

While Beyonce took the stage along with Chris, her husband Jay-Z made a collaboration with Rihanna, Bono and The Edge. Having recorded "Stranded (Haiti Mon Amour)" in different studios around the globe, he and the three musicians performed the song live together for the first time with a full gospel choir and his band backing up.

"Hope for Haiti Now: A Global Benefit for Earthquake Relief" telethon was broadcast from New York, London, Los Angeles and Haiti and was aired commercial-free across ABC, CBS, NBC, FOX, CNN
, BET, the CW, HBO, MTV, VH1 and CMT. Robert Pattinson served as a co-host while Taylor Swift, Alicia Keys, Madonna, Jennifer Hudson and Mary J. Blige were among the performers.
