Katie Holmes is dipping her famous toes into the Twitter pond. Late last month, the actress, designer and single mom, 34, finally joined the microblogging social media site, and has mostly been sharing some of the sights and experiences in South Africa, where she has been filming The Giver with Meryl Streep, Alexander Skarsgard, Jeff Bridges and Taylor Swift. And on Thursday, Nov. 14, Tom Cruise's ex shared a cryptic, inspiring quote from French novelist Andre Malraux.

"Love this. So true," wrote Holmes as she shared a Twitter photo of Malraux's quote, written in type against a sepia-toned background. "The real struggle begins when you have to contend against a part of your own self," begins the quote. "Up to that point, it's all plain sailing. Yet it's only from such inner conflicts that a real man emerges. Yes, we've always to fear the world within ourselves, there's no escaping is."

Two summers ago, of course, Holmes' life transformed forever when she and Tom Cruise divorced after six years of marriage, with the Mania Days actress first filing the papers. The NYC-based Holmes and Yang designer shares daughter Suri, 7, with Cruise, 51.

Little Suri has recently been spotted at her mother's side during her stay in South Africa -- and appears to be featured in a recent TwitPic shared by Holmes.

"My gentle wakeup call from some sweet dreams... #thegivermovie," wrote Holmes beneath one cute snapshot, in which a small child's hands seem to grab Holmes' sleepy face.
