Demi Lovato had a whale of a time at last night's unite4:humanity event in Los Angeles - managing to meet and take a selfie with none other than Bill Clinton.
The 42nd President of the United States,who was in office from 1993 to 2001, looked perfectly happy to pose for a snap with the pink-haired 'Neon Lights' singer, who put the image straight up on her Twitter and her Facebook pages.
She wrote: "Too excited to filter this... NO BIG DEAL - #Selfieswiththeprez.... @billclinton - so nice to meet you!!!!"

Demi - who has 20 million followers more than the man born William Jefferson Blythe III - was also seen catching up with family friend Eva Longoria.
The popstar's half-sister Madison De La Garza played Longoria's daughter Juanita Solis on Desperate Housewives for four years up until its cancellation in 2012, and Longoria called the ex-X Factor USA judge "my sweet Demi" after seeing a collage of snaps of them together posted on Twitter.
Demi also hung out with BFF Selena Gomez at the bash, and looked gorgeous in a black leather dress.
She was spotted leaving with rumoured love interest Wilmer Valderrama, though it is still unknown what the state of their relationship is.
The 21-year-old is in the midst of a North American tour, on which she is being supported by Little Mix, Cher Lloyd and Fifth Harmony.
