Using the handle @msrheasantos, Santos posted her first tweet: "Hi everyone! Finally embracing a new world. Twitter newbie in training."
Santos' second tweet was a photo from Instagram where she also signed up using the same handle @msrheasantos.
Whether she'll be active on tweeting remains a question. Fellow GMA Newser Vicky Morales (@msvickymorales) joined Twitter almost two years ago and has since posted only 24 tweets. To date, she has more than 17,000 followers.
Santos now joins Howie Severino, Connie Sison and Pia Arcangel, among others, in the list of GMA Newsers on Twitter.
Maybe Arnold Clavio is next?
