Ryan Reynolds has posted a comedy throwback video to mark Betty White’s 99th birthday yesterday (January 17).

Sharing a joke clip filmed on the movie’s set with White and co-star Sandra Bullock, Reynolds wrote in his Instagram Stories: “We made this 12 years ago.

In the clip, which was shared in full on YouTube, Reynolds and Bullock are preparing to give fans a behind-the-scenes look at the film when White appears on set, Reynolds saying that White “hates” him.

While Bullock defends their older co-star, White then calls Renolds “Bryan” and mistakes him for her assistant.

White then runs over to Bullock, feigning offence as she discreetly gives Reynolds the finger, before Bullock confronts him and puts him in his place, calling White a “national fucking treasure”.

Calling it the “best picture of the year”, White also said that Reynolds looked “so fucking handsome in his red suit”.
