See New Pics of Michael Jackson's Kids!

Nearly two years after Michael Jackson's death, his sister Latoya and the King of Pop's three children -- Prince, 14, Paris, 12, and Blanket, 9 -- made a rare public appearance on Thursday.

After shopping at Forever 21 and a cell phone accessories cart in Beverly Hills, the foursome stopped by the GBK Kids Choice Lounge, which supports the Red Cross Japanese relief fund.

Co-sponsored by Tiger Beat and Bop, celebrity attendees were able to choose from a one week stay in the Caribbean, a certificate for a glitter tattoo party by Glimmer Body Art, more than 40 titles from the SEGA Genesis Classic Collection Gold Edition, as well as many other goodies.

"I had a wonderful, productive day! Having Japanese food right now. Very good," Latoya, 54, tweeted Thursday night. "Don't forget about Japan! Please keep them in mind and do whatever you can to help."
