Ryan Reynolds isn’t letting anyone forget his hilarious ‘feud’ with Betty White, even on the comedy icon’s 99th birthday. The 44-year-old actor paid tribute to Betty’s milestone occasion with a throwback to the hilarious sketch they performed together in 2009 for Funny or Die. Ryan and Betty had just co-starred together in the rom-com ‘The Proposal’ alongside Sandra Bullock, and the sketch features the pair exchanging jabs with each other behind-the-scenes.
