Oprah Winfrey shared a fun-filled day with Gayle King’s grandson, Luca, wheeling him through her garden to check out the harvest. The occasion marked her very first time ever pushing a baby stroller, she remarked in a video highlight reel from the day. «First harvest day and garden adventure for Luca and my first time pushing a stroller,» Winfrey captioned the clip. «Goes to show you that it's never too late or too early to learn something new.» King's daughter and Luca's mama, Kirby Bumpus, was also on hand, helping the 11-month-old explore the sights, sounds and tastes of the garden.
