For years she's watched her famous brother Jamie Foxx soak up the spotlight, but now it's DeOndra Dixon's time to shine. The 27-year-old sister of Oscar winner Foxx has been named the 2011 Ambassador for the Global Down Syndrome Foundation.

And no one could be prouder of her than her bro. "She's a superstar now," Foxx tells People. "One thing people may not understand is that the love a person with special needs gives you is unfiltered. There is nothing in the way of them loving you and there is nothing in the way of them being upset with you either. You really get the true individual." 

Dixon, who lives with Foxx in Los Angeles, seems to have nothing but love for her brother. "I'm happy to have a big brother to count on, who I love every day," she says.
