One is famous for her "Poker Face", the other is a girl who just wants to have fun.

Between them, Lady GaGa and Cyndi Lauper - pictured above preparing for their interview with CNN's Becky Anderson - have sold tens of millions of records worldwide; now they are in London putting their weight behind a new fundraising initiative from the M.A.C. AIDS fund: "From Our Lips".

Lady GaGa, who recently picked up three gongs at London's BRIT Awards, is known for her wacky style and sensational vocals. She's the lady of the moment, who everyone wants to work with – from Giorgio Armani to Rihanna to Simon Cowell.

Meanwhile, after more than twenty sterling years and global record sales, Cyndi Lauper has proven she's got the heart and soul to keep fans compelled by her every creative move. Throughout her career, the singer-songwriter has promoted gay and lesbian rights, and she continues at the helm of the "True Colors Fund" organizing concerts to show solidarity against discrimination.

Although the pair were born to different generations, their journey to pop fame couldn't be closer. They were both born to American-Italian parents and brought up in New York City, and both started playing and performing music at an early age.

Destined for stardom, and now coming together to promote an important cause, Cyndi Lauper and Lady GaGa will be your Connectors of the Day on Wednesday's Connect the World.

Award-winning Australian artist and film-maker George Gittoes has travelled the world to tell stories from the front lines of war.

For the last forty years, he's worked in area normally reserved only for soldiers and journalists, in countries such as Afghanistan, Iraq, Somalia, Bosnia and Northern Ireland.

Working face to face with those caught up in the crisis of conflict, he uses his artistic interpretation to present his work through painting, photography, video and performance.

His latest film "Miscreants of Taliwood" (2009) is the last in a trilogy of documentaries, showing Gittoes making his way through Pakistan's remote and forbidden North West Frontier.
