Britney changes diaper on floor of Victoria's Secret

How low can she go?

To the floor, apparently.

Just days after saying she is an emotional wreck in an interview with NBC's Matt Lauer, Britney Spears reportedly changed the diaper of her 8-month-old son Sean Preston on the floor of a Victoria's Secret shop in Mission Viejo, California. The pop star reportedly bought some pink G-strings at the store, and when she discovered that she needed to change her son's diaper, she did so on the floor next to the cash register. A shocked sales associate told the New York Daily News, "We don't have the cleanest floors. She just put him down and changed his diaper and then handed it to a sales clerk saying, 'Can you throw this away for us?' We told her that we couldn't put that in our trash." (3:30 p.m.)

Jay-Z donates $30k to New York area schools

Def Jam president and New Jersey Nets co-owner Jay-Z is donating $30,000 toward a student essay-writing contest he launched in December for New York-New Jersey area schools. More than 700 students entered the contest, with the six winners each nabbing $5,000 for their schools.

The contest began as part of a rivalry between Jay-Z and Charlotte Bobcats owner Robert Johnson. The first team to reach 80 points in their December 14 game--the Nets won--agreed to pay up.

"It was great to see the students' school spirit in their essays," Jay-Z said in a statement. "They showed they want a well-rounded education in a comfortable environment. I hope that these donations help them to achieve their goals." (11:00 a.m.)
