Oh, hey Reese ... when did you join Twitter?!

Reese Witherspoon posted a snapshot of herself lounging poolside in a swimsuit while vacationing in the Bahamas today (Aug. 22), proving that she's just like us when she hits the tropics. The 37-year-old actress read the September issue of Vogue -- featuring Jennifer Lawrence -- while working on her tan, captioning the WhoSay photo with, "Loving #theseptemberissue #perfectdayinparadise."

Witherspoon apparently joined Twitter in February, sending out her first post on Feb. 28. But since then, the "Mud" star hasn't tweeted much, randomly throwing up a photo or two here and there.

Yesterday, she tweeted:

Yup, that's Reese's feet and her son Tennessee's bottle. Now THAT'S a Bahama mama.
