Solange Knowles may have a pregnant, world-famous sister, but for the time being, her mommy muse is a different well-known fashionista.

"Kate Moss is a role model for me. She's fabulous," the recording artist told Us Weekly at the "10 Years of Kate Moss and Rimmel" event in London on Thursday. "I mean she's a working mother. Anyone who knows how to juggle those two elements and does it well I'm a big fan of."

Knowles, 25, has a six-year-old son, Daniel Julez Smith, Jr., with her high school sweetheart Daniel Smith, so she knows how stressful it can be balancing motherhood and the celebrity day-to-day.

So how is the aunt-to-be feeling about sis Beyonce and Jay-Z's big news?

"I'm very excited (to be an aunty)!" she exclaimed. "I couldn't be more excited for her -- she's gonna be a brilliant mom."
