U.S. First Lady Michelle Obama is in Cape Town on the last leg of her South Africa tour.  Today, she met with Archbishop Desmond Tutu and told him, gesturing to her children, it's not about us now - it's about them.

Mrs. Obama, who is known for her Let's Move! campaign against childhood obesity, and Archbishop Tutu (who turns 80 in October) did push-ups together when they met at Cape Town's new 55,000-seat soccer stadium, USA Today reported.

The two were there to promote a program for local youths that encourages them to protect themselves against HIV/AIDS and to stay healthy through sports.

Overnight, Mrs Obama's scheduled tour of the apartheid prison Robben Island, which once held former South African President Nelson Mandela, was cancelled due to bad weather that made the ferry journey impossible, AFP reported.

Instead, Mrs Obama toured the District Six Museum, which chronicles the history of a Cape Town neighborhood that was segregated during apartheid.  Mrs. Obama also visited the University of Cape Town, where she gave a speech.

The White House blog will be updating the First Lady's progress, posting links, photos and blog posts of the trip; you can follow along at http://www.whitehouse.gov/youngafrica .
