Mariah Carey remembers Whitney Houston with touching YouTube tribute

Mariah Carey has paid tribute to her late friend Whitney Houston with a touching compilation of their performances together.

The superstars teamed up to record When You Believe for 1998 movie The Prince of Egypt and the track went on to win Best Original Song at the Academy Awards.

They remained friends over the years and Carey cancelled an appearance on TV earlier this month (Feb12) after hearing about the How Will I Know hitmaker's death.

Now Carey's shared her memories of Houston with her fans in a new video of clips posted on her official YouTube.com page.

In a post on her Twitter.com page, she writes, "RememberingWhitney... Whitney, my friend, I love you, I miss you. Your legend lives on forever."
