The charitable star was on hand to support her fiancé, Kinney, and his efforts for Operation Smile. Gaga just returning from Paris Fashion Week rocked a pink fur and black and white hair. She was so moved by Dr Bill Magee's Mission that just $240 can change a child's life forever and repair a cleft lip, she offered to make a generous donation to cause. The recently engaged stars were chatting with event chair and NBC Entertainment President Jennifer Salke and son Henry who was born with a cleft lip. The 15 year old has been championing fundraising efforts determine to help others who are born with the same affliction in developing countries with no access to surgery.
