Obama family

The 15-year-old has taken a summer job serving food at the business in Martha's Vineyard, Massachusetts.

Sasha, using her full name, Natasha, has been accompanied to the restaurant by a contingent of six secret service agents, the Boston Herald reports.

The town has been a favourite location for the Obamas on their summer breaks.

The Oscar winner was joined on stage by Obama, First Lady Michelle Obama, their daughters, Malia and Sasha, and Michelle's mother, Marian Robinson, for the annual event, and even lent her vocals for some Christmas carols with the family, and singer Aloe Blacc.

"Happy holidays to Reese and everyone here tonight and everyone watching at home," the president said before leading the crowd to a countdown that ultimately ended with the famous lighting of the tree.
