See what hanging out with Taylor Swift can do?

Katie Holmes, who is filming a movie with the hit-making singer in South Africa, joined Twitter on Friday – and seems thrilled about it, though she has a ways to go to catch up to Swift's 35 million followers.

"So happy to be on twitter!!!!!! Sending first tweets from South Africa!!!!!" the actress, 34, wrote in her first post.

She also retweeted a candid photo, posted by producer Nikki Silver, of herself and Swift standing with their other cast mates on the set of The Giver.

Holmes recently told E! News that she was "really excited" to make the science-fiction film about an obliviously dystopian society, and which also stars Meryl Streep and Jeff Bridges.
