Kristin Chenoweth made a subtle diss Sunday against her ex-boyfriend Dana Brunetti on Twitter, and he just couldn’t resist the urge to respond to her tweet.

The 46-year-old actress tweeted her satisfaction that the Showtime series The Affair and star Ruth Wilson beat out HBO’s House of Cards — the show Brunetti produces — for Best Drama at the 2014 Golden Globe Awards.

“So happy The Affair won tonight. #deserving love Ruth Wilson xo,” tweeted the The Opposite Sex actress.

Brunetti quickly understood her little passive-aggressive barb and retweeted her message, adding a simple word that says so much.

“Ha,” he added to the retweet.

Chenoweth and Brunetti broke up in November after dating for a year, and It must have stung a bit for the 46-year-old Wicked actress when her ex showed up on the Golden Globes red carpet with his reported new girl, 28-year-old Arrow actress Katie Cassidy.

“Katie is really falling hard for Dana and the feeling is mutual,” a source told E! Online. “She hasn’t felt this way about a man in some time. He just gets her and their time together is always filled with laughter. They’ve been friends for a long time before they got intimate and that’s the main reason why it’s working out so well.”

Meanwhile, Chenoweth has been busy preparing for some upcoming films, including The Boy Next Door with Jennifer Lopez and Hard Sell with Skyler Gisondo.
