Lopez, Anthony to perform duet

Jennifer Lopez will perform a duet with hubby Marc Anthony at the Grammy Awards.

Marc Anthony won a Grammy in 1998 and is nominated for best Latin pop album and best salsa/merengue album this year. He became J-Lo's third husband last June.

The February 13 ceremony will also include a rendition of The Beatles' 'Across The Universe' by Bono, Stevie Wonder, Norah Jones and Alicia Keys.

The song will go on sale online to raise money for the tsunami aid effort. The awards show will also feature performances from U2, Green Day, Alicia Keys and Kanye West.
