The pop star, who adopted two children from the African country, said she's happy that Malawi's former vice president, Joy Banda, is now president.
Banda is the country's first women leader. Former president Bingu wa Mutharika died of a heart attack on April 5.
The singer called Banda "amazing," adding, "She was really into girls being educated in Africa, which is a good thing. So, I'm glad."
As for her new Truth or Dare perfume, Madonna said she's "been trying to develop a fragrance for probably the last 15 years."
"It's never worked out with various companies and different people and trying different fragrances," she said. "They never turned out the way I wanted them to smell."
But Madonna says that was partially due to her expensive taste.
"It's the mass producing part that always gets tricky, because for some reason the fragrances that I like tend to be really expensive," the singer said. "One time I created a smell and I was told the amber, it was like a million dollars to ship from India or something. ... And then they tried to make (a) synthetic (version). This happens a lot and it never smells as good as you want it to smell. That's happened a couple times. Finally I got a smell I like that I can mass produce. Yay!"
Truth or Dare ranges in price from $39 to $68.
Madonna will kick off her "MDNA" concert tour May 29 in Israel.http://www.cbsnews.com/8301-31749_162-57413667-10391698/madonna-praises-malawian-leader-at-fragrance-launch/
