Jay-Z has already pledged his allegiance to George Clooney and Wyclef Jean’s benefit for Haiti, and now his wife has also signed on.

The singer, who recently announced that she would be taking a break this year, will participate in “Hope for Haiti Now: A Global Benefit for Earthquake Relief,” reports MTV News. She will appear in London with Jay-Z, U2’s Bono and The Edge, and Rihanna, but it is unconfirmed if she will perform.

Other celebrities lending their star power to help raise relief for the earthquake-ravaged country include Justin Timberlake, Alicia Keys, Christina Aguilera, Mary J. Blige, Jennifer Hudson, Shakira, and Stevie Wonder.

The two-hour “Hope for Haiti Now” telecast will air commercial-free on Friday at 8 p.m. ET/PT.
