Hilarious moment Malia Obama is caught on camera teasing her sister with a sarcastic thumbs-up sign as Sasha swoons over meeting Ryan Reynolds at their first state dinner

Sasha was beaming when she met Reynolds and can be seen in a photo (left) smiling excitedly as they spoke.

In the background, slightly blurred, Malia is smiling too - all the while raising her two thumbs in direction of her sister, seemingly cheering her on and teasing her at the same time. Malia (upper right), 17, and Sasha (bottom right), 14, attended a state dinner for the first time in their father's presidency. Reynolds, who was born in Vancouver, British Columbia, was one of four actors and actresses who attended the event in honor of new Canadian Prime Minister Justin Trudeau on Thursday.
