This goes to show that social media is not just for the younger generation! The 67-year-old, Goldie Hawn, “tweeted” about the birth of her fifth grandchild, and first granddaughter.

Welcome Rio! Our first baby girl to join our family! @theoliverhudson and Erinn thank you for bringing so much JOY to our lives! #happiness

The Hollywood actress has three children, Wyatt Russell from her present long-term relationship to Kurt Russell, and Oliver and Kate Hudson from her previous marriage to Bill Hudson.

Hawn must have learned her “tweeting” skills from Oliver. The proud father “tweets” photos of his boys camping in their backyard.
