Alli Sims: Recording Music, Still Loving Britney Spears

She's been best known for hanging with Britney Spears, but now her cousin / BFF / personal biatch, Alli Sims, is aiming for a career of her own.

Many celebrity news outlets have been watching Sims' official website closely, and on Monday, Spears' former assistant updated it to include her first song - a cover of "On My Own," from the stage musical Les Misérables.

The newly launched singer says she has a staunch supporter in Britney Spears.

Shrugging off the typical celebrity gossip and rumors that Britney resented her decision to pursue her lifelong dream, Alli Sims, 26, says:

"She heard my songs on the laptop and was like, 'I love this song! This is you singing?' She has always been supportive."

Sims' comments are in slight contrast to recent reports of her estrangement from Spears and collaborations with K-Fed to protect their kids from the train wreck.

As for Spears' parenting skills, which have come under fire from Kevin Federline, his lawyer Mark Vincent Kaplan and others, Sims tells People, "She's a wonderful mom and she is so hands-on. ... Britney loves those babies to death. And they adore her."

Maybe Alli should read our stunning report on Sean Preston and Jayden James from yesterday and see if she's still willing to sing that tune afterward.

When it comes to her music, the Southerner is after a "soulful" sound, and the single on her Web site is "more of a filler song until I get my new stuff recorded. Honestly, we put that one up there because all the other ones I had put down in the past had a little more of a country vibe, and I do not want to go there at all."

Further distinguishing herself from Spears, Alli Sims also says, "I don't dance, I'm not pop. I'm more bluesy, more Norah Jones-ish. I don't want to appeal to just my age group."

Having moved to L.A. after college with a music career in mind, Sims made ends meet by working with noted wedding planner Mindy Weiss and, more recently, for Britney Spears.

"I was doing that for a while, and we had a great time together," Alli Sims says of Britney. "Now I hope everything falls into place, and maybe by January I will have a lot of things under my belt and get to release something. I just want to do what I love. Music is my passion."

Reports say that a solo Alli is making music with the likes of such in-demand producers as Evan Bogart and J.R. Rotem.

No word on whether Rotem has making the same kind of "music" he's made with Alli's "cousin" in the past. We're talking about J.R. tanging Britney wheelbarrow style!
