Alli Sims BSPEARSBLACK062207_04.jpgAlli Sims might be taking a big leap of faith as she attempts to develop a music career for herself, but she's already got fans in high places - like, for instance, her cousin Britney Spears! People is reporting that Britney heard Alli's take on the Les Miserables standard "On My Own" (currently available for listening through Alli's website) stopped Britney in her tracks! According to the magazine, Britney overheard the song blasting out of a laptop, and shrieked "I love this song! Is this you singing?" Sounds like Alli's got a bright future as a singer ahead of her - heck, soon enough she'll need an assistant of her own!
