These 10 Songs Were Meant for Other Singers Janet Jackson could have sung 'How Will I Know' By Evann Gastaldo, Newser Staff Posted Mar 9, 2013 6:30 AM CST 8 comments Comments This 2010 file photo shows Whitney Houston performing in London. (AP Photo/Joel Ryan, file) (Newser) – Can't picture anyone other than Whitney Houston singing "How Will I Know"? Well, Janet Jackson was offered the song first, reports Entertainment Tonight. Nine more songs that were originally intended for someone else: Justin Timberlake's "Rock Your Body" was originally offered to Michael Jackson—as were a few other eventual JT hits. "Don't Cha" (as in, "...wish your girlfriend was hot like me") is bad enough as performed by the Pussycat Dolls ... can you imagine if it had been performed by Paris Hilton? Well, it almost was. Gloria Estefan wrote "Let's Get Loud" for herself, but gave it to Jennifer Lopez in the end. And Lady Gaga wrote "Telephone" for Britney Spears, but ended up releasing it herself. Click for the complete list, including a Chris Brown song that ended up with, you guessed it, Rihanna.
