Beyonce's Sister Solange Plans To 'Spoil' Blue Ivy

'I'm excited to let the baby do whatever it wants,' the younger Knowles laughs to 'In Style' of her niece.

These days, it's hard to thumb through a magazine without stumbling across a famous sister act. The Kardashians and the Braxtons are reigning reality TV divas. The fashionable Fannings have young Hollywood on lock. And the Williams sisters have been known to spark a rap beef when they're not racking up grand slams. But for sheer show-stopping glam, few girl duos gleam brighter than the Knowleses.

Houston natives Beyoncé and Solange have each carved out distinctively impressive lanes, with B owning the pop diva crown while Brooklyn-dwelling Solo has been shutting it down as a turntablist with a playlist as enviable as her closet.

And there's no sibling rivalry from this vantage point: Although Beyoncé celebrated the arrival of [article id="1676906"]baby girl Blue Ivy Carter[/article] with husband Jay-Z just this month, she got a head start on motherhood by playing doting auntie to little sis Solange's one and only, 7-year-old Julez. So how does Solo plan to welcome big sister into the exclusive mommy club?

"This may sound awful, but I'm excited to let the baby do whatever it wants," she teased in the February issue of In Style, "in the same way my sister's done with my son."

Eagle-eyed Beyoncé fans know that nephew Julez has made a number of cameos in the superstar's reel. Among the more adorable was his feature in her Nintendo DSi spot, which found the green-eyed cutie cuddled on a couch with Aunt B as she enjoys some rare offstage downtime. Little J also turned up in the MTV doc "Year of 4," joining the Carters on a trip to Paris. Now, the fashion-blog favorite intends to return the favor.

"I'm going to get her back for all those late-night popcorn sessions and just spoiling my child to no end!" Solo added with a laugh.

When the youngest Knowles isn't DJ'ing, she's hard at work on her forthcoming album, for which she promised the mag she would walk in the funky footprints of '80s hitmakers Jimmy Jam and Terry Lewis.
