Leona Lewis turns down the invitation of President Obama . . .

Leona Lewis turns down the invitation of President Obama . . . Leona Lewis smiles for the cameras as she makes her way to her terminal at the LAX airport on Monday (June 1).

The 24-year-old singer has reportedly turned down an invitation by President Barack Obama to the White House. “Leona was thrilled to be invited to dinner by Obama. She really wanted to meet him and his wife Michelle - who is a big fan and has her Spirit album. They both think she is a strong, inspirational and talented young woman who is a fantastic role model for children,” a source told The Mirror.

“They would love her to get involved in some of their charity projects. But it was really unfortunate that it clashed with her tight schedule to get her second album done,” the source said. “Leona would have felt it a real honor to sing for him too. So if Barack ever asks again, she’ll jump at the chance.”
