Beyoncé Knowles and Shakira are teaming up for a duet.The 'Bootylicious' diva and the hip-shaking Latino singer are collaborating on a track called 'Beautiful Liar' which will feature on the special-edition reissue of Beyoncé's latest solo album, 'B'Day'. Beyoncé - who is currently starring in 'Dreamgirls' - said that deciding to work with Shakira was easy, because she's always been a fan of her music. Beyoncé said: "I've always loved her and I've always wanted to work with her and the song fits perfectly."'Beautiful Liar' tells the story of two women who stand up to a double-dealing man who is trying to bed them both. Beyoncé explained to MTV: "It basically talks about two women. The same guy is trying to get at both of them but instead of them fighting, they're saying, 'He's a beautiful liar, let's not fight, let's stick together - forget him!' I think it's a great concept."Before becoming a global superstar as a solo artist and acclaimed acctress, Beyoncé was the lead singer of Destiny's Child. The reissue of 'B'Day' will also come with a DVD featuring five new videos.
